President-elect Donald Trump’s son-in-law Jared Kushner will reportedly play an important role in U.S. Middle East policy, even though he will not formally be part of the administration.

Regional diplomats and Trump allies recognize that Kushner—who has significant financial interests in the Gulf—has forged deep relationships from his position as a senior White House adviser during the first Trump administration, CNN reported on Friday.

“No one on the incoming team has what Jared has, and that is trust. Jared earned it, he didn’t have it at the beginning. He earned it. That takes time to build,” said a diplomat from a Middle Eastern nation.
