The FBI is now looking into President Biden’s Iran envoy, Rob Malley, three sources familiar with the matter told CBS News.

One source familiar with the matter told CBS News that the FBI was looking at Malley’s handling of classified material. It is unclear if the bureau’s examination encompasses other issues. There was no indication from this source that the FBI considers it a criminal matter at this point.

[If the FBI is investigating, it would usually be in regard to potential criminal violations. If there were no potential criminal issues, the State Department would have handled it through an IG probe. That doesn’t mean that there will be charges, but the FBI doesn’t usually do non-criminal probes involving other agencies — at least in its law enforcement jurisdiction. If there was a counter-intelligence issue, they might be the agency to deal with it, but that opens up even worse potential consequences for Malley and the Biden administration. — Ed]
