Before the FBI would conduct such an investigation....the Director would for sure brief the President. That presupposes this President will even talk to the Director. Some Presidents give the Director a regular meeting, along with other important officials like the CIA Director and of late the DNI.
The FBI would have primary jurisdiction if the compromise was thought to be domestic only....and the CIA would have secondary authority.
Please to remember the CIA Counter Espionage folks and the FBI guys have a very tenuous relationship. Think back to Aldrich Ames closely followed by the FBI's Hanson case. Both were major disasters for each agency.
Throw in the NSA and some other half dozen outfits and the turf wars are monumental.
