Former Sen. Claire McCaskill (D-MO) said Monday on MSNBC’s “Deadline” that there was a path to prosecute Mark Meadows, former President Donald Trump’s chief of staff. Discussing a Washington Post article headlined, “Inside Mark Meadows’s final push to keep Trump in power,” anchor Nicolle Wallace asked, “We know that he knew that there was no evidence of voter fraud. We know that because Bill Barr told him. What do you think Meadows’ sort of body of conduct that could end up under scrutiny really is, Claire?”
