House Select Committee January 6 Attack Investigation

Jan. 6 panel drops Trump subpoena as it wraps up work
(AP) — The House Jan. 6 committee has dropped its subpoena against former President Donald Trump as it wraps up work and prepares to dissolve next week.
Mississippi Rep. Bennie Thompson, the committee’s Democratic chairman, wrote in a letter to Trump lawyer David Warrington on Wednesday that he is formally withdrawing the subpoena.
“As you may know, the Select Committee has concluded its hearings, released its final report and will very soon reach its end,” Thompson wrote. “In light of the imminent end of our investigation, the Select Committee can no longer pursue the specific information covered by the subpoena.”
The committee had voted to subpoena Trump during its final televised hearing before the midterm elections in October, demanding testimony and documents from the former president as it has investigated his role in the Jan. 6, 2021 Capitol insurrection and efforts to overturn his 2020 defeat.
In its final report issued last week, the committee concluded that Trump engaged in a “multi-part conspiracy” to upend the 2020 election and failed to act on the violence. The panel also recommended that the Justice Department investigate the former president for four separate crimes, including aiding an insurrection.
On social media Wednesday evening, Trump and his lawyers construed the move as a victory.

The Biggest Takeaway from the January 6 Report
Rather than conducting a large-scale dragnet, the committee zeroed in on the former president.
By Ronald Brownstein
(The Atlantic) The congressional committee investigating the January 6 insurrection delivered a comprehensive and compelling case for the criminal prosecution of Donald Trump and his closest allies for their attempt to overturn the 2020 election.
But the committee zoomed in so tightly on the culpability of Trump and his inner circle that it largely cropped out the dozens of other state and federal Republican officials who supported or enabled the president’s multifaceted, months-long plot. The committee downplayed the involvement of the legion of local Republican officials who enlisted as fake electors and said almost nothing about the dozens of congressional Republicans who supported Trump’s efforts—even to the point, in one case, of urging him to declare “Marshall Law” to overturn the result.
That reality points to the larger question lingering over the committee’s final report: Would convicting Trump defang the threat to democracy that culminated on January 6, or does that require a much broader confrontation with all of the forces in extremist movements, and even the mainstream Republican coalition, that rallied behind Trump’s efforts?

(Politico Nightly) The executive summary of the January 6 committee report, released earlier this week, has already provided plenty of fodder for discussion and analysis. But Thursday’s release of the full, final report on the historic, 18-month investigation into the siege of the U.S. Capitol and the role of former President Donald Trump in the day’s events is the week’s marquee event, marking the culmination of the committee’s landmark inquiry.
Jan. 6 panel prepares to unveil final report on insurrection
(AP) — An 800-page report set to be released by House investigators will conclude that then-President Donald Trump criminally plotted to overturn his 2020 election defeat and “provoked his supporters to violence” at the Capitol with false claims of widespread voter fraud.
The resulting Jan. 6, 2021, insurrection of Trump’s followers threatened democracy with “horrific” brutality toward law enforcement and “put the lives of American lawmakers at risk,” according to the report’s executive summary.
“The central cause of January 6th was one man, former President Donald Trump, who many others followed,” reads the report from the House Jan. 6 committee, which is expected to be released in full on Thursday. “None of the events of January 6th would have happened without him.”
The committee’s eight chapters of findings will largely mirror nine hearings this year that presented evidence from over 1,000 private interviews and millions of pages of documents. They tell the story of Trump’s extraordinary and unprecedented campaign to overturn his defeat and his pressure campaign on state officials, the Justice Department, members of Congress and his own vice president to change the vote.
The many scandals Trump’s tax records reveal
By the WaPo Editorial Board
In 2020, President Donald Trump and Melania Trump paid no federal income taxes by claiming millions in dubious deductions and carrying over losses from previous years.
Somehow, that’s not the most scandalous detail to emerge following the House’s four-year legal brawl to obtain Mr. Trump’s tax returns. It turns out the Internal Revenue Service did not conduct — let alone complete — mandatory examinations of Mr. Trump’s returns while he was president, despite its own internal policy from 1977 requiring such reviews and the White House’s claims that they were happening.
House committee votes to make public Trump’s tax returns
Panel says IRS did not perform mandatory audits during Trump’s first two years in office despite signs there was much to investigate
The House Ways and Means Committee on Tuesday voted 24 to 16 to release former president Donald Trump’s tax returns, capping a protracted legal and political battle that began when Trump was in the Oval Office.
Democrats have for more than three years pushed to make Trump’s tax returns public, and the documents were finally made available to the Ways and Means Committee late last month after the Supreme Court denied a last attempt by Trump to withhold the records.

Tomorrow afternoon at 1:00, the House Select Committee to Investigate the January 6th Attack on the U.S. Capitol will hold its last public hearing. It is expected to vote on whether to refer former president Trump to the Department of Justice for criminal charges. Then, on Wednesday, it is scheduled to release its report, which is said to be around 1000 pages.
These looming events appear to be causing Trump concern. On Truth Social yesterday, he gave his opinion of the whole proceeding: “They say that the Unselect Committee of Democrats, Misfits, and Thugs, without any representation from Republicans in good standing, is getting ready to recommend Criminal Charges to the highly partisan, political, and Corrupt ‘Justice’ Department for the ‘PEACEFULLY & PATRIOTICLY’ speech I made on January 6th. This speech and my actions were mild & loving, especially when compared to Democrats wild spewing of HATE. Why didn’t they investigate massive Election Fraud or send in the Troops? SCAM!” (The quotation is produced here as it appeared.)
Today he continued to post similar statements.
Meanwhile, Andrew Solender and Alayna Treene of Axios reported today that the Republicans are planning to issue their own 100-page report, focusing on what they say are security failures, claiming that the January 6th committee has “never dealt with the serious issues.” The committee report is expected to discuss security failures.
… House minority leader Kevin McCarthy (R-CA) warned the January 6th committee to preserve all its materials. Chair Bennie Thompson (D-MS) seemed unimpressed. Not only does the committee have to preserve all its materials by law, but it intends to make its material available to the public. “He’s the public. If he wants access to it, all he has to do is go online and he’ll have it,” he told Solender.
GOP shadow committee re-emerges for Jan. 6 report
House Republicans are privately plotting to release their own 100+ page rebuttal timed to the Jan. 6 committee report this week, Axios has learned.
Why it matters: Republicans aim to cast the select committee’s report as partisan by contrasting its expected focus on former President Trump with their concentration on Capitol security.
The precise timing is still being worked out, Axios is told, with Republicans waiting to see what the select committee does at its Monday hearing.

What the Jan. 6 select committee’s final report will look like
A large executive summary describes former President Donald Trump’s culpability for his extensive and baseless effort to subvert the 2020 election, according to people briefed on its contents.
By Kyle Cheney and Nicholas Wu
(Politico) The Jan. 6 select committee’s final report will begin with a voluminous executive summary describing former President Donald Trump’s culpability for his extensive and baseless effort to subvert the 2020 election, according to people briefed on its contents.
The details of the report’s breakdown mirror what the committee has long described as Trump’s “seven-part plan” to subvert the 2020 election to seize a second term he didn’t win. The attack analysis is a detailed breakdown of the actual mob assault on the Capitol — including details about figures who instigated the breach and helped overcome police resistance at significant moments.

Jan. 6 panel brushes off Trump 2024 in critical final sprint
Chair Bennie Thompson said the select committee has a “laundry list” to complete, including the final report and key decisions about criminal referrals.
(Politico) … the select committee is preparing to make some of its weightiest decisions — ones that could not only provide new evidence about Trump’s attempt to subvert the election, but also spoon-feed his political rivals plenty of attack fodder.
Thompson told POLITICO that includes an imminent response to Trump’s lawsuit last week aimed at blocking the committee’s subpoena for his testimony and documents, which Thompson said they’d likely have to file by Friday.
The panel will also need to decide how to handle the intake of new evidence, as the House’s official call for Republicans starts the ticking on the proverbial clock. Thompson said the spigot continues to flow — including a deposition scheduled for Tuesday with at least one witness from the Secret Service — even as the committee looks at an all-but-certain end date in less than two months.
Not to mention the select committee is still preparing a massive final report, a multi-chapter look at Trump’s scheme that lawmakers originally planned to release in the spring. But writing quickly grew increasingly complicated due to ongoing investigative efforts.

House January 6 committee ‘in discussions’ with Trump’s attorneys for him to testify under oath, Cheney says
(CNN) Cheney’s comments came days after CNN reported that Trump’s team formally agreed to accept service of a subpoena issued to him by the House panel seeking documents and testimony from the former president. Publicly, the response by Trump’s team has been limited to a rambling letter sent to committee members that attacked their work and declining to say whether Trump would agree to a sworn deposition.

“This memo is being written to express our anger, disappointment, and complaint that with all of the hundreds of millions of dollars spent on what many consider to be a Charade and Witch Hunt, and despite strong and powerful requests, you have not spent even a short moment on examining the massive Election Fraud that took place during the 2020 Presidential Election, and have targeted only those who were, as concerned American Citizens, protesting the Fraud itself,” Trump wrote in the letter, which is dated Oct. 13.
The document includes numerous photos meant to demonstrate the crowd size at his Jan. 6 rally, as well as a state-by-state breakdown renewing baseless claims of election fraud in five states Trump lost to President Biden.
The Jan. 6 committee votes unanimously to subpoena Trump
(WaPo) Among the revelations presented by the committee on Thursday was a memo suggesting that the plan for Trump to declare the election stolen should he lose was a premeditated strategy hatched even before voters went to the polls.
The committee also provided new evidence that Trump privately understood voters had rejected his reelection bid, including by ordering a likely chaotic immediate withdrawal of U.S. troops from Afghanistan and Somalia just four days after news organizations called the race for Joe Biden.

A guide to the biggest moments in the Jan. 6 hearings so far
As the committee holds what might be its last public hearing on Thursday, Oct. 13, here are the biggest takeaways from this summer’s hearings on the Jan. 6, 2021, attack.
1. The committee holds Trump responsible for the attack on the Capitol
2. Trump was told, repeatedly, that he lost the election
3. The committee raised at least four crimes they think Trump may have committed
4. Trump and his advisers pressured officials to keep him in power
5. The ‘absurd’ idea to pressure Pence to overturn election results
6. The Republican Party apparatus helped Trump try to overturn the 2020 results
7. After the attack, admissions of remorse and pardon requests
8. The terrifying violence, revisited
New evidence to show Trump was warned of violence on Jan. 6
The Jan. 6 select committee’s hearing on Thursday at 1 p.m. is expected to corroborate parts of the more-startling accounts of that day
The likely final public hearing of the House committee investigating the Jan. 6, 2021, attack on the U.S. Capitol is expected to highlight newly obtained Secret Service records showing how President Donald Trump was repeatedly alerted to brewing violence that day, and he still sought to stoke the conflict, according to three people briefed on the records.

Heather Cox Richardson July 12, 2022
Today the House Select Committee to Investigate the January 6th Attack on the U.S. Capitol held its seventh public hearing. This one focused on how former president Trump summoned right-wing extremists to Washington, D.C., on January 6, 2021, in a last ditch effort to overturn the 2020 election.
The committee made it clear that Trump deliberately created the crisis on January 6. …
The committee produced evidence from a number of emails and tweets from Trump and other organizers saying that after the rally, Trump would urge attendees to march to the Capitol, undercutting the argument that the move was spontaneous. In fact, it was long planned.
The committee also introduced evidence that the White House coordinated with members of Congress to encourage the Big Lie and to fight the election results.

Bannon says he will testify at public hearing as contempt trial looms
In a letter, former president Donald Trump told his former chief strategist he will waive his claim of executive privilege, which government lawyers have said never applied
By Isaac Stanley-Becker, Josh Dawsey and Jacqueline Alemany
(WaPo) The claim of executive privilege is disputed by government lawyers. But the effort suggests Bannon is seeking to bolster his defense against contempt of Congress charges filed after he refused to comply with a subpoena from the House committee last fall. A trial on those charges is scheduled to begin July 18, though Bannon has sought to delay the proceedings.

Witness Details Trump’s Rage and Meadows’s Inaction on Jan. 6
(NYT) Cassidy Hutchinson, a former aide to President Donald J. Trump’s final chief of staff, described Mr. Trump insisting that security allow armed protesters to move freely. She added that her boss, Mark Meadows, did little to try to manage Mr. Trump on Jan. 6 and sought a pardon for himself. Mr. Trump, responding on his Truth Social website, denied many of Tuesday’s accusations.
(NYT) Cassidy Hutchinson recently sat for a fourth interview with the committee behind closed doors and, with new counsel advising her, informed the panel of previously unknown information that lawmakers felt needed to get out quickly, according to a person familiar with the investigation. The panel had also grown concerned for Hutchinson’s security, so lawmakers decided to keep her planned testimony quiet for as long as possible, the person said on condition of anonymity because they weren’t authorized to speak on the record.

The January 6 Hearings Are Working
And even the staunchest Trump allies know it.
By Molly Jong-Fast
The greatest proof that the hearings are working? Trump Republicans are largely ignoring them. As George Conway told me, “Lots of Republicans want this to happen and they’re secretly rooting for Liz. Senate Minority Leader Mitch McConnell wants someone to stick the knife in [Trump]; he just doesn’t want that someone to be him.”
Perhaps the most decisive piece of evidence that the hearings are working is an ABC poll, done after the first three hearings, showing that “nearly 6 in 10 Americans believe former Pres. Trump should be charged with a crime for his role in the Jan. 6 riot.” It’s hard to get Americans to agree on anything, let alone something as polarizing as this. As Bill Kristol tweeted, “58% of Americans: Trump bears ‘great deal’ or ‘good amount’ of responsibility for Jan. 6. 60%: Committee is fair and impartial. 29%: Hearings make me more likely to support Democrat (19% Republican).”

Navarro pleads not guilty to contempt charges, will face jurors in November
Navarro is the second Trump ally involved in preparations to disrupt the transition of power on Jan. 6, 2021, set for trial this year on contempt of Congress charges.
Former Trump administration adviser Peter Navarro will go on trial in mid-November on charges that he defied a subpoena of the Jan. 6 select committee.
U.S. District Court Judge Amit Mehta set the schedule after Navarro’s attorneys initially requested an April 2023 trial date to avoid interfering with Navarro’s plans to market a pro-Donald Trump book he will release in September.

Heather Cox Richardson June 16, 2022
On CNN this morning, Representative Jamie Raskin (D-MD), a member of the House Select Committee to Investigate the January 6th Attack on the U.S. Capitol, said: “New evidence is breaking every single day now. Suddenly, a lot of people want to tell the truth.”
After the committee’s third public hearing today, we can see why. The window for getting onto the good side of the investigation by cooperating with it is closing, and the story the congress members are laying out makes it clear that those sticking with Trump are quite likely in legal trouble.
[retired federal judge J. Michael] Luttig hammered home that Trump’s scheme was an attempt to overturn the rule of law and to destroy our democracy. And, he warned, the danger is not over. Trump and his supporters remain “a clear and present danger to American democracy.”
Luttig’s testimony was powerful, but even more extraordinary was a statement he released before today’s hearing. Luttig, for whom both Eastman and Senator Ted Cruz (R-TX) clerked, warned that “January 6 was…a war for America’s democracy, a war irresponsibly instigated and prosecuted by the former president, his political party allies, and his supporters.”
Stephen Colbert: T****’s Lawyers Knew Overturning Election Was A Crime
John Eastman and the rest of the lawyers advising the former president knew that his plan to overturn the election was a crime, and today’s Jan. 6th Committee hearing revealed that the insurrectionist mob got alarmingly close to getting their hands on VP Mike Pence that day.
Today’s Jan. 6 committee hearing is about the details of the intense pressure campaign against Pence on Jan. 6. Much of today will be devoted to unpacking this line from Vice Chair LIZ CHENEY’s (R-Wyo.) opening statement last Thursday:
“Aware of the rioters’ chants to ‘hang Mike Pence,’ the president responded with this sentiment: ‘maybe our supporters have the right idea.’ Mike Pence ‘deserves’ it.”
In what could be some of the most dramatic moments today, the committee will juxtapose these three things:
• Trump’s comment about Pence deserving to hang.
• The increasingly frantic pleas from Pence aides that the vice president was in danger
• The details of Pence’s whereabouts in the Capitol as rioters came extraordinarily close to him and his Secret Service agents searched for a safe route of escape.
One of the intended takeaways from today’s presentation is that Trump — knowingly — almost got Pence killed.
Greg Sargent: Decoding Liz Cheney’s big hint about John Eastman — and Donald Trump
We still don’t know if Trump or his co-conspirators will ever face a criminal investigation relating to Jan. 6. But Cheney just dropped a big hint about the case the committee will make against both Eastman and Trump.
… In the video, Cheney reminded us the committee has convincingly demonstrated that Trump was extensively informed he’d lost. Cheney then said Thursday’s hearing will focus on Trump’s relentless pressure on Pence to subvert the electoral count in Congress.
“President Trump had no factual basis for what he was doing, and he had been told it was illegal,” Cheney continued. Despite this, she added, Trump “plotted” with Eastman and others to overturn the election on Jan. 6, 2021.
Trump’s pressure on Pence to abuse his role as president of the Senate by delaying the election’s conclusion is the key that unlocks this whole scandal. Eastman concocted a bogus legal justification for Pence to secure this delay, which would allow states to revisit the voting, find it fraudulent and certify sham electors for Trump, overturning his loss.

Next Jan. 6 hearings to focus on how Trump’s ‘big lie’ fueled rioters
(WaPo) The second public hearing by the House select committee investigating the Jan. 6, 2021, insurrection will focus on then-President Donald Trump’s baseless claims that the 2020 election was stolen — dubbed the “big lie” — and how those false claims were connected to the pro-Trump mob that attacked the U.S. Capitol that day in a bid to stop the certification of Joe Biden’s electoral college win, lawmakers on the bipartisan panel said Sunday.
In a background briefing with reporters on Sunday night, a select committee aide said the hearing on Monday, led by Chairman Bennie G. Thompson (D-Miss.) with an assist from Rep. Zoe Lofgren (D-Calif.), will also dissect the fundraising apparatus that was built around the “big lie” to drive up the post-election cash haul.
“We will reveal information about how the former president’s political apparatus used these lies about fraud, about a stolen election, to drive fundraising, bringing in hundreds of millions of dollars between Election Day 2020 and January 6,” a committee aide said.

(Politico) The memo informed Pence’s ultimate decision to rebuff pressure from Trump to reverse the outcome of the election. Pence announced his decision the next day, when he traveled to the Capitol to preside over the Jan. 6 meeting of the House and Senate. His decision, in a letter that closely tracked Jacob’s memo, inflamed a crowd of thousands of Trump supporters that the president had called to Washington to protest his defeat.

9-10 June
Heather Cox Richardson June 10, 2022
…a great deal of the power of the committee’s presentation last night came from the fact that many of its key witnesses were themselves members of Trump’s inner circle. Those witnesses included his attorney general, William Barr; Trump campaign spokesperson Jason Miller; Chairman of the Joint Chiefs of Staff General Mark Milley; and Trump’s own daughter and son-in-law, Ivanka Trump and Jared Kushner. They established that Trump indeed knew he had lost the election, that he nonetheless stoked a movement to keep him in power, and that when the insurrectionists attacked the Capitol to stop the counting of electoral votes, he refused to intervene to protect lawmakers, law enforcement officers, or the law.
…As Trump’s attack on his daughter indicates, last night’s hearing appears to have exacerbated the chaos in the Republican Party as Trump and his supporters struggle to cling to power in the face of damning evidence that they tried to destroy our democracy.
The Jan. 6 Hearing Put a True-Crime Drama on Prime-Time TV
The first night of the Jan. 6 hearings was serious public service, but it told an engrossing story with the tools of a limited series drama.
(NYT) Representatives Bennie Thompson, Democrat of Mississippi, and Liz Cheney, Republican of Wyoming, led the first hearing on the Jan. 6, 2021, attack, which was packaged like a prime-time news special.
The first night of the congressional Jan. 6 hearings was not an entertainment. It was deadly serious reality, offering a panorama and a terrifying close-up of a real nightmare: The attempt, through violence, to effectively end American democracy by overturning the will of the voters and keeping President Donald J. Trump installed in an office that he lost.
But the hearings were also television, fighting for attention in a cacophonous media environment. This is not just me speaking as a TV critic. The committee itself acknowledged this by bringing on James Goldston, a former ABC News president and producer, to shape the broadcast, and by airing it, unusually, in prime time.
This was not simply a dutiful time capsule for the historical archives. This was TV meant to break through, and to matter, now.
5 Takeaways From the First Jan. 6 Hearing

At Least 20 Million Watched Jan. 6 Hearing
… Fox News, the most-watched network in cable, did not carry the hearings live, instead sticking with its usual prime-time lineup.
The Fox News hosts Tucker Carlson and Sean Hannity dedicated their shows to Jan. 6, and both had the hearing playing live in a split screen — but the feed from Congress was muted while the hosts spent two hours belittling the committee’s efforts.
January 6 Committee Opens With a Narrative MasterClass
Teasers, hooks, special guests, mic drop—what we just saw is must-see TV.
(Mother Jones) That Trump and his cronies tried to overthrow election results has been clear for more than a year to those who are paying attention.
But what if you haven’t been?
Well, the January 6 Committee has made a deft play to get your attention, and they’re doing it by deploying all the tricks of a limited-run HBO series or podcast. First, they use structure—a “seven-part plan” to overthrow a free and fair election, as Reps. Bennie Thompson (D-Miss.) and Liz Cheney (R-Wyo.) told us, and they’re going to devote an episode to each part of that plan. Care to see which members of Congress begged for a presidential pardon for their role in the coup? Tune in to episode 4!
In the prologue, they laid out where they’re going to go, and which night you can tune in for what part. They’re dropping little previews of the juicy depositions (I especially appreciated the way they let Jared show himself to be the callous traitor he is) and other evidence to come. And then they cut to a film, a timeline of sorts, of what went down that day—maybe 10 minutes of how the rioters talked of their plans, how they started to breach the Capitol, how Trump egged them on from the bandstands and then via Twitter, how the police fought for their lives and the lives of members of Congress.
Liz Cheney got her chance to rebut her dishonorable peers. She didn’t miss.
By Dana Milbank
(WaPo) Liz Cheney was addressing her fellow Republicans. But more than that, she was speaking to posterity.
“I say this to my Republican colleagues who are defending the indefensible,” she said at Thursday night’s opening hearing of the Jan. 6 House select committee. “There will come a day when Donald Trump is gone, but your dishonor will remain.”
Over 35 minutes, she delivered a methodical indictment of Trump’s role in planning and fomenting the violence, drawing occasional gasps and murmurs from the media, staff and lawmakers in the room.
It’s beyond the Jan. 6 committee’s mandate to explain how so many people who began with honorable instincts ultimately retreated to join Trump. And there is probably no convincing them, nor the tens of millions they have deceived, to correct course now. But the committee’s work gives hope that the dishonorable will, at least, earn history’s rebuke.
