Former Secretary of State Hillary Clinton no longer has a security clearance.

Clinton had her security clearance withdrawn in August “at her request,” State Department official Charles Faulkner wrote to Senate Judiciary Committee Chairman Chuck Grassley, R-Iowa, in a letter released Friday.

Five other individuals whom Clinton had designated as researchers had their clearances withdrawn in September.

The letter was dated a day after the clearances for Cheryl Mills and four other names, which were redacted, were withdrawn. Mills served as Clinton’s chief of staff during her tenure at the State Department.

“At her request, former Secretary Clinton’s security clearance was administratively withdrawn on August 30, 2018,” the letter said. “On September 20, 2018, security clearances were administratively withdrawn for Cheryl Mills, [redacted], [redacted], [redacted], and [redacted]. As we previously informed the committee, these individuals had been granted access to classified information through a request made by Secretary Clinton designating them as researchers.”

The letter to Grassley was part of the department’s investigation into the mishandling of classified information when Clinton used a private email server when she was the nation’s top diplomat.

Clinton request came a week after President Trump revoked the security clearance of former CIA Director John Brennan. The status of Clinton’s clearance at the time was not publicly known.
