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

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.

As it wraps up its investigation, with a final report on findings and recommendations expected by the end of this year, the House committee on Thursday spent significant time rehashing points from their previous hearings.

One such finding was Trump's knowledge ahead of Election Day that mail-in ballots would favor Joe Biden and his plan ahead of time to declare victory that night.

Rep. Adam Kinzinger, R-Ill., focused partly on the failed efforts by Trump to litigate his loss in court -- a major focus of the June 13 hearing.

"In the past hearings we said the committee identified 62 election lawsuits filed by the Trump campaign and allies between Nov. 4, 2020 and Jan. 6, 2021," Kinzinger said on Thursday. "Those cases resulted in 61 losses and only a single victory, which did not affect the outcome for any candidate."

Rep. Elaine Luria, D-Va., in her remarks about Trump's direct efforts to overturn the election, replayed previously seen deposition from former Attorney General Bill Barr. Barr told the committee that Trump's false allegations about voting machines was "crazy stuff" -- footage first aired in a June hearing.
