House Intelligence Committee Chair Mike Turner has made information concerning a “serious national security threat” available to all members of Congress to review, the committee said on Wednesday.

While Turner and the White House remained vague on what the threat entailed, two sources and a US official tell CNN the threat is related to Russia. Multiple sources familiar with the intelligence characterized it as “very sensitive.”

One of the sources who has seen the intelligence confirmed that “it is, in fact, a highly concerning and destabilizing” Russian capability “that we were recently made aware.

Earlier Wednesday, Turner sent his Congressional colleagues a letter saying the urgent matter is “with regard to a destabilizing foreign military capability.”

Turner said in the letter to his congressional colleagues that the House Intelligence Committee voted on February 13 to make certain information available for lawmakers to review and says members have time to view this between Wednesday and Friday.

Turner is also calling on President Joe Biden to declassify “all information relating to this threat.”

National Security Adviser Jake Sullivan said he had personally reached out to set a meeting with top lawmakers on national security committees before Turner warned publicly of what he termed the “serious national security threat.”

Sullivan signaled some frustration with Turner for preempting that meeting, scheduled for Thursday with his public statement, saying he was “a bit surprised Turner came out publicly today”

“I reached out to see Turner,” Sullivan said. “Turner has gone out publicly. I’m going to go see Turner tomorrow. That’s where I want to leave things for today.” He declined to elaborate on the nature of the threat.
