Trump Reacts to Schwarzenegger's exit from Celebrity Apprentice

US President Donald Trump fired back at Arnold Schwarzenegger, who claims to have quit "The Celebrity Apprentice", saying the actor was sacked from the show because of his "pathetic" ratings.

"Arnold Schwarzenegger isn't voluntarily leaving the Apprentice, he was fired by his bad (pathetic) ratings, not by me. Sad end to great show," Trump tweeted.

Schwarzenegger quickly wrote, "You should think about hiring a new joke writer and a fact checker."

Trump has been blaming Schwarzenegger for "The Apprentice" declining ratings.
