Tiffany Trump's father-in-law Massad Boulos to become senior presidential adviser on Arab affairs

​President-elect Trump on Sunday said he would appoint Massad Boulos, a billionaire from Lebanon whose son Michael is married to Tiffany Trump, to serve as his senior adviser on Arab and Middle Eastern affairs.

"Massad is an accomplished lawyer and a highly respected leader in the business world, with extensive experience on the International scene," Trump wrote in a message on Truth Social.

"He has been a longtime proponent of Republican and Conservative values, an asset to my Campaign, and was instrumental in building tremendous new coalitions with the Arab American Community," he continued. "Massad is a dealmaker, and an unwavering 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!"

Tiffany Trump, the president-elect's youngest daughter, married Michael Boulos in 2022, with President-elect Trump walking his daughter down the aisle.

Massad Boulos is just the latest family figure in Trump's orbit to land a post with the administration. On Saturday, Trump said he would nominate Charles Kushner, the father of his son-in-law Jared Kushner, as ambassador to France.

Jared Kushner and his wife, Ivanka Trump, had roles in Trump's first term but are not expected to work in Trump's second administration.

The elder Boulos was a critical figure for Trump in the swing state of Michigan, campaigning for the president-elect among Arab American voters. Trump ended up winning the state again.

He is also a billionaire and the leader of the family business SCOA Nigeria, an automotive company.

Boulos will likely play a role in any effort Trump makes to get a peace deal in the Middle East, which has been riven with war since the Oct. 7 Hamas attack on Israel.

Israel's government has since led a bloody war on Gaza, which has threatened at times to break out into a wider regional war as Iran and Israel have lobbed missile attacks at each other.

Israel and Hezbollah, the Iran-backed militant group based in Lebanon, did reach a ceasefire deal this week.
