The CIA is opening an "exploratory" investigation into the general conduct of ex-CIA director David Petraeus, who resigned last week after acknowledging an affair.
CIA spokesman Preston Golson says the investigation by the CIA's inspector general "doesn't presuppose any particular outcome."
Lawmakers questioned top CIA and FBI officials about the affair Thursday, during hearings originally scheduled to investigate the Sept 11 attacks in Benghazi, Libya.
Petraeus biographer and girlfriend Paula Broadwell was found to have classified information in her possession, apparently from her time researching Petraeus' career.
The FBI cleared Petraeus of mishandling classified information, but reserve army officer Broadwell is under investigation and her security clearance has been suspended.
Petraeus will testify before Congress Friday about the events in Benghazi.
