Director Chris Wray said the January riot at the U.S. Capitol was “criminal behavior, plain and simple. And it’s behavior that we, the FBI, view as domestic terrorism.” Testifying before the Senate Judiciary Committee, he also argued against claims by U.S. Capitol Police officials that the FBI did not warn them about threats to the building.

Lawmakers once again grilled law enforcement officials Thursday about the Jan. 6 riot at the U.S. Capitol. Acting Chief Yogananda Pittman pushed back against suggestions that Capitol police failed to prepare adequately. Many lawmakers agreed that Capitol law enforcement should not shoulder all of the blame. But members maintained police should have been more prepared than they were.

Law enforcement officers tasked with protecting the U.S. Capitol blamed intelligence failures for the Jan. 6 incursion that left five people dead and dozens injured. At a joint Senate committee hearing on Tuesday, witnesses said they never saw a warning the FBI sent about the potential for violence the day Congress met to certify the results of the presidential election. “We properly planned for a mass demonstration with possible violence,” former Capitol Police Chief Steven Sund said.

The Democratic chairman of the House Homeland Security Committee accused former President Donald Trump in a federal lawsuit on Tuesday of inciting the deadly insurrection on Jan. 6 at the U.S. Capitol. The suit from Rep. Bennie Thompson, D-Miss., is part of an expected wave of litigation over the riot. It also names as defendants Trump’s personal lawyer Rudy Giuliani and several extremist groups that participated in storming the Capitol.

Lawyers for former President Donald Trump on Friday called the second impeachment case against him an “unjust and blatantly unconstitutional act of political vengeance.” They dismissed the prosecution’s arguments that Trump’s claims of election fraud and calls for his supporters to take action amounted to incitement of the insurrection that occurred Jan. 6 at the U.S. Capitol.

Former President Donald Trump’s defense team will take the floor once again on Friday. Democratic impeachment managers on Thursday wrapped up their argument that rioters who invaded the Capitol were acting on the president’s orders.
