In the Aug. 24 letter, which marks a significant expansion of the Republican senator's inquiry, Sen. Charles Grassley writes, "Since the [intelligence community inspector general] IC IG made a referral to the FBI pursuant to 50 U.S.C. §3381, has Secretary Clinton's security clearance been suspended pending the outcome of the inquiry?"
The suspension of a clearance is standard practice, a kind of interim step taken to preserve security until an investigation is complete, according to current and former military intelligence officials.
"If you have a circle of people and they are the source of the leak, all of them, normally would be suspended from their positions, they can't go in the building," Chris Farell, a former special agent for Army counterintelligence, told Fox News. Farrell now works as an investigator for Judicial Watch, which is suing for Clinton records.
"The clearances would be suspended by the security manager and it would be made known that there is an active investigation into the loss of classified information, and no information should be shared with these individuals pending the outcome," Farrell added.
In the four-page letter, Grassley said, based on a letter from Clinton's personal attorney David Kendall, that neither he nor his associate Katherine M. Turner had sufficient security clearances to handle the emails -- which contained at least two highly classified documents identified by the intelligence community's IG.
"... neither Mr. Kendall nor Ms. Turner have a security clearance at a sufficient level to be a custodian of TS/SCI (Top Secret/Sensitive Compartmented Information) material," he wrote.
Grassley's letter also for the first time laid out a timeline that is key to the FBI investigation. The senator said Clinton provided copies of the emails to her lawyer in December 2014. Classified intelligence was identified in the emails in May 2015, but it wasn't until July that the State Department, in a highly unusual move, supplied Kendall with a safe -- a further admission that while Clinton says no documents stamped classified were sent or received by her, the State Department was concerned enough to provide secure storage to Kendall.
