FBI Director James Comey met privately with members of the Senate Intelligence Committee for nearly three hours Friday afternoon as lawmakers continued to grapple with the fallout over national security adviser Mike Flynn’s resignation in the wake of reports that he talked about U.S. sanctions with the Russian ambassador in late December.

The members of the intelligence panel emerged from the meeting, held in a secure room in the Senate basement used for classified briefings, tight-lipped, refusing to confirm that Comey had spoken to them, even though reporters spotted Comey entering and exiting the meeting.
