An Arab self-made billionaire said he regretted backing Donald Trump after the Republican frontrunner called for all Muslims to be barred from entering the United States.
"I wrote an article supporting him [in a leading Gulf newspaper in August]," Khalaf Al Habtoor, who has featured on the Forbes rich list, told NBC News on Tuesday. "I said we are fed up with the politicians, they have destroyed the Middle East ... I wrote we need a successful businessman like Mr. Trump."
