The White House put in place a ban on new interim security clearances in November, but allowed those who had already received interim clearances to continue working with them, Politico reported Tuesday night.

A November 7 email obtained by Politico did not spell out the reasoning behind the new ban on interim security clearances.

The security clearance process in the White House has come under intense scrutiny recently following the revelation that staff secretary Rob Porter remained in a high-level position, even as the background check process turned up domestic abuse accusations from his ex-wives.

FBI Director Christopher Wray said on Tuesday that the FBI completed Porter’s background check in January, however, the White House security office had not yet completed its determination on Porter’s security clearance, according to the New York Times.

Jared Kushner, a White House adviser and President Donald Trump’s son-in-law, has also reportedly been working on an interim security clearance for a year, along with several others.
