Kushner, a senior adviser to the president, has been able to see some of the nation’s most sensitive secrets even as his background investigation has dragged on for more than a year.

White House officials have privately discussed concerns that Kushner’s clearance faces obstacles, according to people familiar with internal conversations, who spoke on the condition of anonymity to describe private talks. Among the potential problems: repeated amendments that he had to make to a form detailing his contacts with foreign officials. Two U.S. officials said they do not expect Kushner to receive a permanent security clearance in the near future, The Washington Post reported last week.

In the meantime, Kushner has maintained an interim clearance that gives him access to top-secret and sensitive compartmented information — a rare level of access to hold for a long period of time, experts said. His elite position has allowed him to meet with foreign officials around the world and read the classified intelligence prepared daily for the president.
