Donald Trump has taunted Arnold Schwarzenegger, his replacement as host of The Celebrity Apprentice, saying the actor was "destroyed" in TV ratings.
Former action movie star Schwarzenegger responded by suggesting that Trump turn his attention to his work as the nation's new president.
"So much for being a movie star", wrote the USA president-elect, who described himself as a "ratings' machine".
Schwarzenegger has taken over the new iteration of Trump's old management show, titled "The New Celebrity Apprentice", which has miffed Trump.
CNN Money has noted that it is an unusual move for Donald Trump to criticize Celebrity Apprentice, especially as Trump has retained the role of executive producer on the NBC show.
The president-elect took time Friday to note that the "Terminator" star was "swamped" in his "Celebrity Apprentice" debut "by comparison to the ratings' machine, DJT". "Now compare him to my season 1", he added.
Schwarzenegger, afterwards, quoted Abraham Lincoln in a video on Twitter and asked Trump to study the words of Lincoln's Inaugural Address in 1861, in which he spoke of bringing all Americans together.
He also wrote: "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".
Schwarzenegger, a Republican who served two terms as California governor but who has said he did not vote for Trump, responded swiftly. We must not be enemies. According to Mr. Trump, Arnold Schwarzenegger is not enough good for his TV show, the first episode of which in 2008, watched more than 11 million people. This is a show with such a large stake in the Monday TV audience, it's just harder to compete with it and there was likely a bigger pool of available viewers two years ago when the show was last on the air.
Trump will be inaugurated as USA president on Jan 20.
