Ousted FBI Director James Comey said the law enforcement agency expected Attorney General Jeff Sessions to recuse himself from the Russia investigation, but said he could not discuss details because they were classified.

“Our judgment was that he was very close and inevitably going to recuse himself,” Comey said, later adding that the FBI had some classified information that might make it impossible for Sessions to continue with any involvement in the matter.

“We were also aware of facts I can’t discuss in an open setting that would make his continued involvement in a Russia investigation problematic,” Comey said. 

{mosads}Comey offered the remarks in testimony to the Senate Intelligence Committee under questioning from Sen. Ron Wyden (D-Ore.). Comey said the FBI had “facts … that would make his continued involvement in a Russia investigation problematic.”

Sessions recused himself from decisions on Russia after news broke that he didn’t reveal conversations with Russian officials last year.
