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).

Actress Sandra Oh cursed CBS and Paramount networks over Stephen Colbert's show cancellation, citing concerns about culture and free speech during her guest appearance.
