WASHINGTON — The security clearance of White House senior adviser and presidential son-in-law Jared Kushner has been downgraded, significantly reducing his access to classified information, according to two people informed of the decision. Kushner had been operating with an interim clearance at the “top secret/sensitive compartmented information” level for more than a year. Now he is authorized to access information only at the lower “secret” level, according to a White House official and a person familiar with the decision, both of whom spoke on condition of anonymity. Neither source was authorized to discuss the decision publicly. Tuesday’s news set off rampant speculation among Trump allies that Kushner’s days in the White House might be numbered. On the same day, the departure of a third Kushner ally in the West Wing in as many months was announced. And the selection of a Kushner ally to serve as Trump’s 2020 campaign manager appeared to suggest the campaign could provide Kushner with a convenient place to land after his White House duties end. Kushner lost his access to the nation’s deepest secrets after chief of staff John Kelly ordered that White House officials with interim clearances pending since before June 1, 2017, be cut off if they hadn’t received permanent clearances by last Friday. A White House official confirmed that Kelly’s order has been implemented. President Donald Trump could have reversed Kelly’s decision and unilaterally offered Kushner a clearance, but deferred to Kelly. Kushner is one of dozens of White House aides who have been working without permanent security clearances for the better part of a year. His attorney said that Kushner’s ability to do his job won’t be affected by any change to his clearance. “Those involved in the process again have confirmed that there are dozens of people at Mr. Kushner’s level whose process is delayed, that it is not uncommon for these clearance reviews to take this long in a new administration, and that the current backlogs are now being addressed,” said Peter Mirijanian, a Kushner spokesman. Kushner’s portfolio once included the US relationships with China and Japan and a host of domestic priorities, including infrastructure, trade and economic development. But his freewheeling reach in the foreign policy space - which was viewed as undermining Secretary of State Rex Tillerson — already had been curtailed somewhat under Kelly. Still, Kushner is reportedly said to have reviewed the highly secret presidential daily brief and has been in the room for some of Trump’s most consequential domestic and foreign policy decisions. White House press secretary Sarah Huckabee Sanders told reporters on Tuesday that she would not comment on individual security clearances but called Kushner “a valued member of the team, and he will continue to do the important work that he’s been doing since he started in the administration.” The Washington Post reported on Tuesday that officials in at least four countries had privately discussed ways they could manipulate Kushner by taking advantage of his complex business arrangements, financial difficulties and lack of foreign policy experience. — AP
