James Clapper, a former director of national intelligence, said Sunday he was “absolutely” unaware that the FBI had a confidential source in contact with three Trump campaign associates during the presidential election.

“I did not know about it nor would it be appropriate for any DNI to know about the specifics of informants, their identities, or what they’re doing on the part of the FBI. There are lots of reasons for that, not the least of which is confidentiality and the protection of the informants,” Clapper told CNN’s “State of the Union.”
