David Letterman is subtly showing support for his successor Stephen Colbert after CBS' shock cancellation of "The Late Show."

David Letterman and his YouTube channel uploaded a 20-minute anti-CBS compilation following Stephen Colbert's 'Late Show' cancellation.

The FCC chairman called out at the "partisan left's" reaction to Stephen Colbert's cancellation by CBS on Monday, saying they were acting like they were losing a "loyal" spokesperson.

Stephen Colbert announced "The Late Show" was cancelled three nights after revealing his summer mustache on air. Coincidence?

Monday night's (July 21) show also featured kiss cam-style pop-ins from supportive fellow talkers Anderson Cooper, Jimmy Fallon, Jon Stewart and Adam Sandler.

Fox News host Greg Gutfeld is the ratings king of late night with 3.1 million average viewers, despite what Stephen Colbert may be telling his audience.

“Love you Stephen,” Severance actor Adam Scott wrote in the comments of Colbert’s Instagram clip. “This is absolute bullshit, and I for one am looking forward to the next 10 months of shows.” Jon Batiste, the show’s former bandleader, called Colbert “The greatest to ever do it,” via Instagram comments.
