Jan. 6 Panel Abruptly Sets Tuesday Hearing on ‘Recently Obtained Evidence’

The House committee investigating the Jan. 6 attack on the Capitol on Monday abruptly scheduled a hearing for Tuesday afternoon to hear what the panel called “recently obtained evidence” and take witness testimony.

The hearing is scheduled for 1 p.m., according to a news release issued by the committee, in which it provided no other details about the surprise session.

The panel has held a series of hearings this month laying out the findings of its nearly yearlong investigation, but it had not been scheduled to have any additional sessions this week, with no legislative action planned and lawmakers scattered across the country.

The panel has continued to gather evidence and record interviews with witnesses even as it presents its hearings. At the end of each session, lawmakers often issue calls for more witnesses to come forward.

In recent days, the committee obtained and has been poring over hours of footage shot by a documentary filmmaker who was embedded with President Donald J. Trump, his family and members of his inner circle immediately before, during and after the riot.

But aides refused to divulge what additional evidence they planned to present on Tuesday or who would be testifying, saying that the panel was concerned for the security of its witnesses.

The committee had been planning at least two more hearings for July, according to its chairman, Representative Bennie Thompson, Democrat of Mississippi. Those hearings were expected to detail how a mob of violent extremists attacked the Capitol and how Mr. Trump did nothing to call off the violence for more than three hours.

Previous hearings have focused on the pressure campaigns Mr. Trump launched against the Justice Department, state officials and his own vice president, as he sought to cling to power.
