The House of Representatives has impeached President Trump for the second time. But the Senate isn't expected to start a trial until after President-elect Joe Biden is inaugurated. CBS News political contributor and host of the "Article One" podcast Molly Hooper spoke with CBSN about the president's change of tone in a video released Wednesday night, as well as her interview with former Senate Sergeant At Arms Terry Gainer, who discussed the investigation into the assault on the Capitol and how it's affecting the Capitol Police.
