No surprise here really if you've been watching any of Stephen's recent segments on The Late Show With Stephen Colbert. He hates Donald Trump. But one extended comment you won't necessarily hear on The Late Show is that Colbert definitely, definitely, definitely regrets not being harsher on Trump when Trump was on the show back in 2015 (I've embed that video below).
Colbert goes a bit deeper into it in the SiriusXM interview above with Bill Carter (on The Bill Carter Interview), eventually straight-up calling Donald Trump a coward. All gloves are off at this point. I'd love for Trump to appear on The Late Show one more time and see the real Stephen roast this guy.
