Piers Morgan to Daily Show's Jon Stewart: worry about your job

CNN's Piers Morgan has apparently had it with the criticism coming from "The Daily Show's" Jon Stewart.

"If I were Jon Stewart, I'd stop obsessing with CNN and start worrying about the younger, funnier [Daily Show contributor] John Oliver getting his job..." Morgan wrote in a tweet Wednesday.

On Tuesday, Stewart delivered a heavy critique of cable news in general, but also targeting CNN (as he often does) for its often-speculative and unsubstantial reporting on the Navy Yard shooting, as the story was breaking.

"We’re in an abusive relationship with CNN!" Stewart said on his show. "And it’s time we kicked those bastards to the curb, because we have to remember, this network was created by Ted Turner, not Ike Turner.”

Oliver was Stewart's longterm and well-received fill-in earlier this year while Stewart was working on a movie.
