House Permanent Select Committee on Intelligence chairman Mike Turner (R-Ohio) warned Wednesday that members of Congress have received “information concerning a serious national security threat.”

“I am requesting that President Biden declassify all information relating to this threat so that Congress, the Administration, and our allies can openly discuss the actions necessary to respond to this threat,” Turner added in a statement.

A spokesman for the panel did not immediately respond to a request for further information.

Asked about the nature of the threat during a White House press conference, National Security Adviser Jake Sullivan declined to say whether it was a foreign military threat or if he could assure Americans they should not worry.

“In a way, that question is impossible to answer with a straight ‘yes,'” he said.

“We can, and will, and are protecting the national security.”

Sullivan added that he was “surprised” by Turner’s statement because a briefing for the Gang of Eight, comprised of the top Republican and Democratic leaders in both chambers of Congress, is scheduled for Thursday.

He also emphasized that the House Intelligence chairman’s declassification request was “ultimately” a decision for President Biden.
