Stephen Colbert shares a pointed message after President Trump celebrated CBS's stunning decision to end 'The Late Show.' Late-night hosts Jon Stewart, John Oliver and others rally behind Colbert.

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

David Letterman delivered a fiery rant against CBS and parent company Paramount for cancelling Stephen Colbert’s “Late Show,” calling the decision “gutless” and “pure cowardice” as he labeled his successor a martyr of the network.
