Plaskett began laying out a nearly minute-by-minute account of what happened once the Capitol was breached by playing audio of police dispatchers and video of the violence from Jan. 6, some of which had not previously been released publicly.

"Multiple Capitol injuries. Multiple Injuries," an officer says in one audio clip. 

The dispatcher says, "You've got a group of about 50 charging up the hill on the west front just north of the stairs. They are approaching the wall." 

An officer is heard pleading for reinforcements, saying that rioters were pulling down security gates and throwing metal poles at officers. An officer also said the people began to throw explosives. 

In another piece of audio, a dispatcher responds to an officer and declares the Capitol attack a riot just before 2 p.m. ET. She also played video of rioters outside the Capitol attacking police and breaking down windows.

Twitter told CNBC the morning of the second day of the impeachment trial that it would continue its ban against former President Trump regardless of whether he runs for office in 2024.

House managers have been using particularly incendiary tweets from Trump as far back as July to make their case of how he incited the Jan. 6 riot at the Capitol.

If convicted at the trial, Trump would become ineligible to run for public office again. Twitter said the outcome of the impeachment trial does not change its decision to permanently remove Trump from the platform.

The trial has resumed after a brief recess with Del. Stacey Plaskett of the U.S. Virgin Islands speaking.

The impeachment trial has recessed for 15 minutes following Dean's presentation.

Rep. Madeleine Dean, D-Pa., became emotional as she recounted how Jan. 6 unfolded while she was inside the Capitol, saying the events that day are "forever etched in our memories." 

Dean said she went to work that day "with a sense of excitement" because it was the beginning of her second term in the House and was the first time she would participate in the counting of electoral votes in Congress. 

She said that she stood in the House gallery with her colleagues as they observed Republicans challenging the Arizona results for Biden, and moments later they heard on police radios that the building had been breached. 

"Someone shouted up to us, 'Duck!'" she recounted, saying they all then got down on the floor. "Shortly after, there was a terrifying banging on the chamber doors." 

"I will never forget that sound," she said, choking up, saying that she made panicked calls to her husband and son. 

Dean said the chaos that day was inspired by Trump, adding, "You saw a man willing to attack anyone and everyone who got in his way, and you saw a man who thought he could play by different rules."

Explaining the many warnings from law enforcement agencies and others ahead of the Capitol riot, Del. Stacey Plaskett cited an NBC News report that said online forums popular with conservatives and far-right activists were filled with threats and expectations of violence before the rally that preceded the deadly events.

Del. Stacey Plaskett argued that Trump knew his supporters would be violent because of warnings from law enforcement and specifically encouraged them to engage in such acts. 

Plaskett, of the U.S. Virgin Islands, said that just as Trump spent months spreading his "big lie," he also spent months "cultivating groups of people" who followed his commands and engaged in violence. 

"He fanned the flame of violence," Plaskett said. "The violence was what he deliberately encouraged." 

The lawmaker played a clip from the presidential debate in September 2020 when Trump addressed far-right extremists such as the Proud Boys "to stand back and stand by." She said that the group thereafter adopted that phrase as their slogan. 

She also showed video footage of a caravan of Trump supporters surrounding a Biden campaign bus in October in Texas as it traveled from San Antonio to Austin, which resulted in two cars colliding. The Biden campaign said the pro-Trump trucks tried to run the bus off the road. 

The FBI announced afterward that it would investigate the incident.
