Glenn Kirschner and Frank Figliuzzi join Lawrence O’Donnell to discuss the latest on the Capitol invasion investigation. Kirschner, a former federal prosecutor, says the units assigned to the investigation indicate it could involve members of Congress, and Figliuzzi, a former FBI official, says investigators may scrutinize Donald Trump’s inaction during the insurrection.

At least 18 states are taking security precautions after the U.S. Capitol attack on Jan. 6. NBC’s Frank Figliuzzi says we are looking at an “almost permanent urgency inside our country,” and that we are going to see an increased security presence for the “foreseeable future.”
