The State Department acknowledged on Tuesday that it can’t tell if Iran has used any of the money it’s recovered under the Iran nuclear agreement, an estimated $3 billion so far, to fund terrorist activities.

“We don’t know,” State Department spokesman John Kirby said when asked if any of the money has been diverted to terrorists. “We don’t have perfect knowledge on what has actually been freed up for them, and we don’t have perfect knowledge of how every dollar of that is going to be spent.”
