“I think this is all pretty public,” Murphy said of members of Congress inviting extremists to Washington on the day of the riot. “They’ve been quite public about their efforts to bolster the President’s call to use Jan. 6 as the last stand in this bid to remain president.” Another Jan. 6 congressman, Maryland Democrat Jamie Raskin, told CBS Sunday that Tuesday’s hearing will reveal the “fundamental significance of a meeting that took place at the White House on Dec. 18,” after which Trump sent out the tweet asking if supporters will be coming to DC on January 6th. “People are going to hear the story of that tweet and then the explosive effects it had on Trump’s world and specifically among domestic violent extremist groups — the most dangerous political extremists in the country at the time,” Raskin said.

A “dereliction of duty”

Murphy also suggested that the Jan. 6 panel may present video of Trump’s White House adviser Pat Cipollone’s interview last week to the committee as part of its hearing on Tuesday. “I imagine you’re going to hear things from Mr. Cipollone, but also from others who have been in the White House,” he said. Cipollone met with the committee for nearly eight hours on Friday. He did not answer questions from CNN as he entered or left the room. His appearance was the result of months of negotiations between his lawyers and the January 6 panel over what topics could be discussed. He had previously met informally with the committee in April. Cipollone’s meeting with the panel came less than two weeks after former Trump White House aide Cassidy Hutchinson testified before the committee last month in a blockbuster hearing. Hutchinson described her experience in the White House as someone close to Trump’s inner circle in the days leading up to and including the Capitol uprising and also shared details of her conversations with Cipollone. Cipollone was among the few people who spent time with Trump as he watched the Capitol uprising unfold on television from a dining room outside the Oval Office, according to two sources familiar with the committee’s investigation. The committee heard from other witnesses, who said that Cipollone, along with other senior Trump advisers, including Ivanka Trump and Dan Scavino, were with the President at various points during that time, and Cipollone could have help shed light on Trump’s state of mind. violence was taking place. Lofgren, meanwhile, told Tapper that Cipollone “was able to provide information on basically all of the critical issues that we’re looking at and that includes the President — what I would call a dereliction of duty on the day of January 6th.” CNN’s Annie Grayer, Zachary Cohen and Ryan Nobles contributed to this report.
