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.
Wow, the ratings are in and Arnold Schwarzenegger got "swamped" (or destroyed) by comparison to the ratings machine, DJT. So much for....

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.
