President-elect Donald Trump announced Sunday that he is tapping his daughter Tiffany’s father-in-law, Massad Boulos, as his senior presidential adviser on Arab and Middle Eastern affairs.

“Massad is an accomplished lawyer and highly respected executive in the business world, with extensive experience on the international stage,” Trump, 78, wrote on Truth Social.

“He has long been a champion of Republican and conservative values, an asset to my campaign, and has been instrumental in building tremendous new coalitions with the Arab American community,” he added.

Born in Lebanon, Boulos runs Nigeria-based Boulos Enterprises, which manufactures and sells mechanical equipment and motorcycles. According to reports, his net worth is estimated to be in the billions of dollars.

Tiffany, who Trump revealed was pregnant in October, tied the knot with Michael Boulos in 2022.

“Massad is a dealmaker and a steadfast supporter of PEACE in the Middle East. “He will be a strong advocate for the United States and its interests, and I am pleased to have him on our team!” Trump continued.

On Saturday, Trump announced Charles Kushner, the father of his son-in-law Jared Kushner, as his choice for ambassador to France.
