Former national security adviser Michael Flynn's security clearance suspended

The Defense Intelligence Agency announced the suspension on Wednesday.

Flynn stepped down amid revelations he misled administration officials about discussions he had with Russia’s U.S. ambassador.

“We have taken the administrative step of suspending Mike Flynn’s access to classified information pending a review,” Defense Intelligence Agency (DIA) spokesman James Kudla said.

“We take this standard administrative action when questions arise concerning an individual’s compliance with security clearance directives.”

The DIA has been the custodian of Flynn’s security clearance since his time there as director from 2012 to 2014. A security clearance is not necessarily tied to a position, but generally a period of time, meaning individuals such as Flynn can retain their clearance after resignation.

Federal government guidelines on classified information state “foreign influence” as a security concern that could prompt the revocation of a clearance.

“Foreign contacts and interests may be a security concern if the individual ... is vulnerable to pressure or coercion by any foreign interest,” state the guidelines.

In his resignation letter, Flynn wrote that he “inadvertently briefed the vice president-elect and others with incomplete information regarding my phone calls with the Russian ambassador.”
