Donald Trump taunts new 'Celebrity Apprentice' host

Donald Trump has taunted Arnold Schwarzenegger, his replacement as host of The Celebrity Apprentice, saying the actor was destroyed in TV ratings.
    
The US president-elect who describes himself as a ratings machine, took to twitter saying, "So much for being a movie star."
    
In response, the actor called on him to work for all Americans as aggressively as he works for ratings.
    
Monday's season launch was seen by an estimated 4.9 million people - down 43% on the last season premiere in 2015.
    
Schwarzenegger has received mixed reviews for his debut as the new star of the show.
