WASHINGTON — Jared Kushner, senior adviser and son-in-law to President Trump, had his security clearance downgraded Friday, sharply limiting his access to some of the nation’s most sensitive secrets amid concerns raised by the ongoing investigation of his background, two White House officials said Tuesday.

Kushner was one of several White House officials who received a memo Friday announcing that because of their interim security clearances, their status was being downgraded from the “Top Secret/SCI” level to the “Secret” level, a far lower level of access to classified information.

The memo came after White House Chief of Staff John Kelly had set a Friday deadline for all staffers operating under an interim clearance to have their temporary clearance revoked, and after Kelly came under scrutiny for his handling of domestic-abuse allegations against former staff secretary Rob Porter – who had also been operating under an interim clearance.

But there was uncertainty over whether Kushner would receive a special carve-out or exception.

Politico first reported the news of the memo.

Because he had an interim clearance, Kushner was not supposed to be able to see the president’s daily intelligence briefing or have access to other top-secret program information, one administration official said. But the rules were not enforced with regard to the access rules for the president’s son-in-law.

Earlier this month, a top Justice Department official alerted the White House that significant information requiring additional investigation would further delay Kushner’s security-clearance process, The Washington Post reported last week.

Kushner’s inability to obtain a final clearance has frustrated and vexed the White House for months. As someone who meets regularly with foreign officials and reads classified intelligence, he would typically have a fast-tracked background investigation, security-clearance experts said.

Friday’s downgrade represents a significant loss of access for Kushner, who routinely attended classified briefings, received access to the President’s Daily Brief intelligence report and issue requests for information to the intelligence community.

A “secret” document could be a diplomatic cable from a U.S. embassy to the State Department, discussing the internal politics of that country. The “Top Secret/SCI” category – SCI stands for “Sensitive Compartmented Information” – by contrast could include details of U.S. programs such as drone targeting in Pakistan or covert operations conducted by special forces. It also could include high-level private discussions between senior government leaders.

Mark Lowenthal, president of the Intelligence & Security Academy and a former U.S. intelligence official, said Kushner’s downgraded clearance level is “a very severe limitation” and will hurt his ability to manage the Middle East peace process.

“This is a very severe limitation because some of the information passing through the White House is more highly classified than ‘secret,’ ” Lowenthal said. “He can no longer see the President’s Daily Brief, and it also means there are certain meetings he can’t be in, because most [National Security Council] meetings will involve materials above the ‘secret’ level. The briefings he will get will have to be severely watered down.”

Bradley Moss, a national security lawyer, said Kushner’s status will deny him the most sensitive information pertaining to Middle East peace negotiations.

“It completely undermines his ability to be fully informed in the context of any discussions and negotiations,” Moss said. “He’s not going to have access to a lot of the intelligence on the ground, on any intercepted communications between countries involved in the negotiations, and he’s not going to be able to get full-detailed background information on the major players. I’m sure they’ll produce a reduced version for him, but it won’t give him the full range of information.”

William Antholis, a national security council official under former President Bill Clinton who now directs the Miller Center at the University of Virginia, said if Kushner’s role in negotiating Middle East peace is merely to be a “goodwill ambassador,” then his “secret” level clearance will be good enough.

“But if it’s actually to carry forward narrow technical details about the negotiations, then he will be limited in his effectiveness,” Antholis said. “In the best cases, negotiations are informed by the most sophisticated intelligence capabilities we have. If you’re a negotiator, you want to know the motives, the must-haves and the can’t-do’s that your counterparts have.”

Last week, Kelly refused to comment on Kushner’s personal status but did offer a general statement in support of him.

“I will not comment on anybody’s specific security clearance situation or go beyond the memo released last week,” Kelly said in a statement then. “As I told Jared days ago, I have full confidence in his ability to continue performing his duties in his foreign policy portfolio including overseeing our Israeli-Palestinian peace effort and serving as an integral part of our relationship with Mexico. Everyone in the White House is grateful for these valuable contributions to furthering the President’s agenda. There is no truth to any suggestion otherwise.”

But Kushner’s access immediately appeared threatened when Kelly issued the new policy earlier this month blocking staff members with interim clearances from receiving top-secret information. The changes were prompted by intense scrutiny that has followed domestic-abuse allegations against Porter, the president’s former staff secretary, who was also working under an interim top-secret clearance.

The move put a “bull’s eye” on Kushner, a senior official told The Post.

Kelly had told associates that he was uncomfortable with Kushner’s uncertain security-clearance status and unique role as both a family member and staffer, according to people familiar with the conversations, and has said he would not be upset if the president’s son-in-law and his wife, Ivanka Trump, left their positions as full-time employees.

On Friday, Trump said he would defer the question of Kushner’s access to his chief of staff.

“I will let General Kelly make that decision, and he’s going to do what’s right for the country,” the president said during a news conference. “And I have no doubt that he will make the right decision.”
