OOPS: Kushner loses access to top-secret intelligence.

Kushner is not alone. All White House aides working on the highest-level interim clearances — at the Top Secret/SCI-level — were informed in a memo sent Friday that their clearances would be downgraded to the Secret level, according to three people with knowledge of the situation.

The SCI acronym stands for sensitive compartmented information, a category of information that comes from sensitive intelligence sources and must be walled off.

The memo was not signed by chief of staff John Kelly, but it comes as the retired Marine general and other top White House aides are grappling with the fallout of a scandal involving former White House staff secretary Rob Porter, which revealed that dozens of White House aides had yet to receive permanent clearances but nonetheless had access to some of the country’s deepest secrets.

It’s the right move, but it also indicates that staffing remains a problem for this White House.
