The FBI is offering a reward for information leading to the arrest of a former Air Force counterintelligence specialist who defected to Iran in 2013.

The FBI is offering $200K for ex-Air Force agent Monica Witt, accused of defecting to Iran in 2013 and leaking US defense secrets years ago.

The FBI said Thursday that it's still trying to locate Monica Witt, who is accused of defecting to Iran in 2013 and revealing highly classified U.S. intelligence.
