Officials in at least four countries have privately discussed ways they can manipulate Jared Kushner, the president’s son-in-law and senior adviser, by taking advantage of his complex business arrangements, financial difficulties and lack of foreign policy experience, according to current and former U.S. officials familiar with intelligence reports on the matter.

Among those nations discussing ways to influence Kushner to their advantage were the United Arab Emirates, China, Israel and Mexico, the current and former officials said.

It is unclear if any of those countries acted on the discussions, but Kushner’s contacts with certain foreign government officials have raised concerns inside the White House and are a reason he has been unable to obtain a permanent security clearance, the officials said.

Kushner’s interim security clearance was downgraded last week from the top-secret to the secret level, which should restrict the regular access he has had to highly-classified information, according to administration officials.
