Billionaire Saudi Prince Alwaleed is making nice toward President-elect Donald Trump, after he demanded that Trump exit the primary race last year.

Back in December 2015, the Saudi prince acted as if he was in a position to direct U.S. politicians.

Reportedly the richest of many Saudi Princes, Alwaleed Bin Talal demanded that Trump exit the race after Trump called for a temporary ban on Muslim immigration following the San Bernardino massacre of Americans by two Muslims — an immigrant woman and the son of an immigrant.

The prince is supposedly worth roughly $24.8 billion — not as much as Trump’s other billionaire critics, Mark Zuckerberg, for example — but enough to be comfortable when socializing with Bill Gates, Michael Bloomberg or Carlos Slim, the Mexican part-owner of the New York Times.

The prince has already donated tens of millions of dollars to set up pro-Islam advocacy centers at several U.S. universities, including Harvard and Georgetown.
