Trump impeachment trial live updates: Biden says charge 'not in dispute' in 1st comments on acquittal

Rep. Ted Lieu, D-Calif., asserted that Trump failed to show remorse for how his behavior incited the riots. Lieu cited Trump's failure pay his respects to U.S. Capitol Police Officer Brian Sicknick who died during the assault on the Capitol.

"President Trump not only failed to show remorse or take accountability, he made clear he is just beginning. For days, he did not address the nation after this attack. We needed our commander-in-chief to lead, to unite a grieving country, to comfort us. But what did President Trump do?," Lieu said. "Nothing, silence."

Lieu says that enhanced protection around the Capitol is necessary because Trump has not admitted that he lost the election. Lieu argued that his lack of remorse is important as Trump will 'undoubtedly' cause future harm.

"He does not say the one sentence that would stop future political violence, 'the election was not stolen.' He still hasn't said that sentence" Lieu said. "That is why National Guard troops in full body armor still patrol outside."

Lead House impeachment manager Rep. Jamie Raskin suggested the senators do what Thomas Paine told us to do, "use our common sense."

"Trump knew exactly what he was doing in inciting the Jan. 6 mob. Exactly. He had just seen how easily his words and actions inspired violence in Michigan. He sent a clear message to his supporters. He encouraged planning and conspiracy to take over capitol buildings and threaten public officials who refuse to bow down to his political will," Raskin said. "Is there any chance Donald Trump was surprised by the result of his own incitement? Let's do what Thomas Paine told us to do, use our common sense. The sense we have in common -- as citizens. If we don't draw the line here, what's next? What makes you think the nightmare with Donald Trump and lawmaking and violent mob is over?"

"January 6th was not some unexpected, radical break from his normal law-abiding and peaceful disposition. This was his state of mind. This was his essential M.O.," he said.

Lead House manager Rep. Jamie Raskin, D-Md., cited the plot to kidnap Michigan Gov. Gretchen Whitmer as an earlier example of inciting his base.

Raskin asserted that the protest at the Michigan state capitol was a "dress rehearsal" for the Jan 6 riot.

"The siege of the Michigan State House was effectively a state-level dress rehearsal for the siege of the U.S. Capitol that Trump incited on January 6th," Raskin said. "It was a preview of the coming insurrection."

Rep. Ted Lieu, D-Calif. began speaking after Raskin about Trump's lack of remorse.

House impeachment manager Rep. Diana DeGette cited an analysis that found mentions of "civil war" quadrupled on Parler in the hour after Donald Trump said "show strength."

"We also have another perspective from this moment: online extremist chatter. At the same time as the people in the crowd shouted, 'Take the Capitol building,' as President Trump said, 'show strength,' a person posted to Parler saying, 'time to fight, civil war is upon us,'" Degette said. "Another user said, 'we're going to have the civil war. Get ready.'" An analysis found members of civil war crime quadrupled on Parler in the hour after Donald Trump said, 'show strength.' When insurrectionists got to the Capitol, they continued those rally cries."
