About 17 months ago, Senator Chuck Grassley, chairman of the Senate Judicial Committee, sent a letter to the State Department inquiring into the status of former Secretary Clinton's clearance.  After all the Comey enumerated "carelessnesses" and the information released since then on her server being hacked by foreign nationals and, of course, copies of everything stored on Weiner's laptop (yuck), he was interested to know if they ever took action.

Over a year and a half after that letter, they finally responded that HRC "voluntarily surrendered" her TS clearance on August 30, 2018.

Knowing how she hates, hates, hates bad optics, there is no way she volunteered to do anything like that.  There must have been another "Brennan" revocation in the works, and she wanted to preemptively pretend she gave it up on her own -- for no reason -- because "did nothing wrong -- other people had private email accounts."

Clearances for 5 others were also revoked/surrendered including her aid, Huma Abedin.  The others were listed as "Clinton's researchers", and the names were redacted from the list sent to Grassley.

As usual, the story was released on a Friday as part of the normal news dump, to prevent it from being a prominent story once the weekend news hits the Monday cycle.

If anyone has ever had a clearance, you know it's highly unusual for anyone to ever volunteer to have their clearance terminated.  And one of the reasons top Executive branch officials keep theirs is in case they are asked to consult or assist their replacements and need access to classified information or spaces.

I guess there's nobody in the Trump WH needing to call Hillary at 3am.   

If she ever does hold another office  , maybe she thinks cancelling and preventing a revocation will not keep her from passing another clearance investigation?  Who knows.  One step further removed from government
