It's been a week since Donald Trump left the presidency. But since his second impeachment trial is underway, he's still a big late-night topic. “We’ve still got a few loose ends from the last administration we’ve got to clear up, like inciting a murderous mob to attack the Congress and overthrow democracy,” Stephen Colbert said on last night's Late Show. “Just bits and bobs.” Meanwhile, James Corden joked on The Late Late Show: "Earlier today, all 100 senators were sworn in as jurors for Donald Trump’s upcoming impeachment trial, which starts on Feb. 8. The trial is to determine if the attack on the Capitol by thousands of people wearing flags that said ‘Trump’ and hats that said ‘Trump’ is the fault of — get this — Trump."
