Chairman Bennie Thompson, D-Miss., said the committee needs to hear from the person they say is at the center of the story of what happened on Jan. 6: Trump.

“We want to hear from him,” Thompson said. “The committee needs to do everything in our power to tell the most complete story possible and provide recommendations to help ensure nothing like Jan. 6 ever happens again.”

Thompson said speaking with Trump goes beyond the committee’s “fact-finding” and is a question about accountability to the American people.

“He is required to answer for his actions,” he said.

Thompson said the committee recognizes subpoenaing a former president is an extraordinary step, which is why the panel will "take this step in full view of the American people."

The committee presented evidence the Secret Service voiced worry for Pence after Trump bashed him in a tweet for not blocking certification of the Electoral College results.

"POTUS just tweeted about Pence, probably not going to be good for Pence," one agent said in a chat with a colleague released by the committee Thursday.

"POTUS said he lacked courage. Over 24K likes in under 2mins," the colleague responded.

Former Twitter employee Anika Collier Navaroli, in testimony featured Thursday, said that rioters "were literally calling for [Pence's] execution," partially "in response to this tweet."

The committee played new footage of House Speaker Nancy Pelosi speaking to former Vice President Mike Pence as Trump supporters were in the middle of storming the Capitol. The contents of that footage is below, as the two discussed how they would ultimately certify the 2020 election results.

At 4:22 p.m. Pelosi was videotaped saying:

"We're trying to figure out how we can get this job done today. We talked to Mitch [McConnell] about it earlier. He's not in the room right now but he was with us earlier and said, "Yeah, we want to expedite this." And hopefully they could confine it to just one complaint, Arizona. And then we could vote and that would be you know, then just move forward with the rest of the states.

"The overriding wish is to do it at the Capitol," said Pelosi, as the committee displayed a photo of Pence presumably on the phone with her while watching news footage on a separate cellphone.

"What we are being told very directly is it's gonna take days for the Capitol to be OK again. We've gotten a very bad report about the condition of the House floor. Defecation and all that kind of thing as well. I don't think that that's hard to clean up. But I do think it is more from a security standpoint of making sure everybody is out of the building and how long will that take?"

At 4:30 p.m. Pelosi said:

"I just got off the phone with the Vice President and I got off with the Vice President-elect," Pelosi said after her call with Pence and supposedly Kamala Harris.

"So I'll tell you what she said, yeah. But what we left the conversation with cause he said, he had the impression from Mitch [McConnell] that Mitch wants to get everybody back to do it there," Pelosi said.

In never-before seen footage, House Speaker Nancy Pelosi is seen reacting to the events of Jan. 6 in real time. Pelosi spoke to or called various officials, including Virginia Gov. Ralph Northam and then-acting Attorney General Jeff Rosen.

"We've got ... to finish the proceedings or else they will have a complete victory," Pelosi is heard saying as she is leaving the Capitol complex while rioters gather outside.

Later, Pelosi was informed that lawmakers still on the floor were putting on tear gas masks in anticipation of a breach.

"Can you believe this?" Pelosi responded.
