During a special edition of The Bill Carter Interview, the new The Late Show host shed his Colbert Report persona to introduce audiences to the “real” Stephen Colbert and spoke bluntly to veteran television journalist Bill Carter about his single interview with Republican presidential candidate Donald Trump.

Trump appeared on ‘The Late Show’ in Sept. 2015, before the candidate had clinched his party’s nomination, when the idea of a Trump candidacy seemed much more far fetched. Colbert doesn’t “regret the attempt” he made to press Trump during the interview, but does “regret that that’s the only bite he’s going to get at the apple.”

“I would have [Trump] on [The Late Show] tomorrow, but he’s a coward,” Colbert said.
