In the week after CBS/Paramount cancelling "The Late Show," Stephen Colbert repeatedly hit back — with backup from his rivals and David Letterman.

Former late-night host David Letterman slammed Paramount and CBS on Friday for their treatment of Stephen Colbert, suggesting the cancellation may be linked to avoiding trouble with Trump.

What’s happening now is not only wrong, it goes against what we must stand for as a nation," said Robert Suttmann, president of Local 802 American Federation of Musicians.

In just the first six months of this year, the show booked 43 left-leaning political guests — and zero conservatives — leading all late-night programs in partisan tilt.

David Letterman took aim at his former employer, CBS, over the cancellation of 'The Late Show With Stephen Colbert.

Bob Odenkirk is 'not remotely concerned about' Stephen Colbert despite the cancellation of 'The Late Show,' and thinks his career will mirror Conan O'Brien's: 'We're gonna see lots more.'

A review by Fox News Digital found that left-wing journalists and other media figures made hundreds of appearances on "The Late Show with Stephen Colbert."

Former Fox News firebrand Bill O’Reilly is gloating over the cancellation of The Late Show, saying host Stephen Colbert only has himself to blame for failing to invite more conservative guests—such as himself.
