State Department revokes Hillary Clinton’s security clearance at her request according to the letter released on Friday by a top GOP senator.

Clinton’s clearance was withdrawn on Aug. 30, according to a letter from the State Department to Senate Judiciary Chairman Chuck Grassley (R-Iowa), which he released

“We would like to provide you with an update on the status of former Secretary Clinton’s security clearance and the ongoing administrative review about former Secretary of State Hillary Clinton and other current and former department officials,” Charles Faulkner, the acting assistant secretary of legislative affairs, wrote to Grassley.

The State Department added in the letter to Grassley that five of Clinton’s aides had also had their security clearance revoked.

Four of the names are redacted, but one aide listed in the email is Cheryl Mills, who worked as Clinton’s chief of staff.

“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,” Faulkner added.

Clinton in 2016 was investigated for her use of a private email server during her tenure as secretary of state. No charges were filed against Clinton, who was running for president at the time of the probe.

Recently President Donald Trump revoked former CIA Director John Brennan’s security clearance, and the White House has said he is reviewing several other clearances of former top officials. Clinton’s name was not on the list of those said to be under review.
