President-elect Donald Trump announced that Massad Boulos, the father-in-law of Tiffany Trump, will serve as a senior advisor on the Middle East at the White House. Boulos, a billionaire businessman, played a role in Trump's efforts to win over Arab American voters during the campaign. He will provide counsel to Trump on Arab and Middle Eastern affairs. This announcement comes just a day after Trump revealed that he will nominate Jared Kushner's father, Charles Kushner, as the U.S. ambassador to France.
