Donald Trump taunts Arnold Schwarzenegger for low ratings in Apprentice spin-off
Donald Trump has taunted Arnold Schwarzenegger for bringing in low ratings in a spin-off from the president-elect's old reality television show Celebrity Apprentice.
In a tweet, Mr Trump referred to himself as a "ratings machine" and said Schwarzenegger "got "swamped" by comparison.
He said "so much for being a movie star" and "now compare him to my season 1".
Mr Trump added: "But who cares, he supported Kasich & Hillary," referring to Ohio Republican governor John Kasich and Democrat Hillary Clinton, who both ran against him.
Schwarzenegger is a moderate Republican who said in October that he would not vote for Mr Trump, calling it a choice of "your country over your party".
He is hosting The New Celebrity Apprentice, in which Mr Trump retains a producing stake.
Schwarzenegger responded by saying the president-elect should work as hard to represent all Americans as he did for TV ratings.
The California governor also quoted Abraham Lincoln's first inaugural address: "We are not enemies, but friends. We must not be enemies."
Schwarzenegger tweeted: "I wish you the best of luck and I hope you'll work for ALL of the American people as aggressively as you worked for your ratings."
