Federal prosecutors have been presenting evidence to a grand jury in Washington, D.C., on whether former White House aide Cassidy Hutchinson may have lied to Congress in her testimony related to the Jan. 6, 2021, attack on the U.S. Capitol, two sources familiar with the matter told CBS News. Hutchinson, a former aide to White House chief of staff Mark Meadows, drew the ire of President Trump's base when she testified in 2022 before the House committee tasked with investigating the 2021 Capitol attack.
