In historic move, House Jan. 6 committee votes to subpoena Trump

The committee revealed new evidence it said showed the Secret Service was aware of threats of violence prior to the insurrection, worrying over social media posts prior to Jan. 6 and what it viewed the day of the attack on the Capitol.

One tip received by the agency said that the Proud Boys, a far-right white chauvinist group, "think[s] that they will have a large enough group to march into D.C. armed and will outnumber the police so they can't be stopped."

"Their plan is to literally kill people. Please please take this tip seriously and investigate further," the tip read.

"Right wing groups responding across the nation and establishing 'quick reaction forces' in Virginia," one Jan. 5, 2021, Secret Service email the panel said it uncovered read.

On the day of the attack, just before the pro-Trump mob moved toward the Capitol, agents voiced growing concern over the number of weapons seized or seen.

"With so many weapons so far, you wonder how many are unknown. Could be sporty after dark," one agent wrote in a message to a colleague.
"No doubt. The people at the Ellipse said they are moving to the Capitol after the POTUS speech," a second agent responded.

The committee plans to hold a vote on subpoenaing former President Trump during today’s hearing, sources familiar with the matter tell ABC News.

Speaker Pelosi was given a heads up about the committee's decision to vote on the matter, sources familiar with the matter say.

The move comes as the committee has debated for months how to handle a request for his cooperation.

Thompson told me earlier today that a subpoena was not off the table.

It’s not clear whether the committee will formally request former Vice President Mike Pence’s testimony, but committee investigators have been privately negotiating with his counsel for months.

An email exchange dated Jan. 6, 2021, between Pence aide Greg Jacob and attorney John Eastman showed Trump had already been advised that former Vice President Mike Pence could not overturn the 2020 election results.

"Did you advise the President that in your professional judgment the Vice President DOES NOT have the power to decide things unilaterally?" Jacob sent to Eastman.

"He's been so advised," Eastman replied.

A Secret Service message unveiled during the hearing said that Trump was "livid" after the Supreme Court declined to hear a case challenging the election results.

"POTUS is pissed," the message read. "Supreme Court denied his lawsuit. He is livid now."

Cassidy Hutchinson, a former aide to then-White House chief of staff Mark Meadows, also recounted how frustrated Trump was following the news.

"The president was fired up about the Supreme Court decision," she told the committee. "The president just raging about the decision and how it's wrong and 'why didn't we make more calls' and his typical anger outburst at this decision."

"He said something to the effect of, 'I don't want people to know we lost, Mark. This is embarrassing. Figure it out,'" she said.
