David Letterman has finally given his opinion on the cancelation of The Late Show – the franchise that he founded.

Speaking with his former executive producer, Barbara Gaines, in a YouTube video Friday, Letterman called the axing of The Late Show With Stephen Colbert “pure cowardice” and said he doesn’t believe the official line from CBS that the decision was purely about economics (the show has reportedly become a money-loser for the network).

In an interview airing on "CBS Sunday Morning" April 23, the late-night TV host describes his show as a place where, for eight years, people could come "for joy, and light, and levity."

David Letterman unloaded on CBS and Skydance on Friday for cancelling “The Late Show,” which he launched 32 years ago, saying the network had mistreated his successor, Stephen Colbert. In an interview posted to his YouTube channel, Letterman said he does not buy the official explanation that the show was cancelled for financial reasons.

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.
