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

Rumors about the $40 million annual losses appeared to stem from reports published by a media outlet called Puck and the New York Post.

The veteran comedian, 78, shared a video montage of him roasting the TV network during his decades-long career of hosting “The Late Show” from 1993 to 2015.
