House Intel Chair Turner warns of 'serious national security threat,' urges Biden to declassify

House Intelligence Committee Chairman Mike Turner is urging President Biden to declassify information related to a "serious national security threat."

"Today, the House Permanent Select Committee on Intelligence has made available to all Members of Congress information concerning a serious national security threat," Turner, R-Ohio, said in a statement Wednesday.

"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," he added.

Fox News Digital obtained the notice sent to congressional members Wednesday, which pointed to "an urgent matter with regard to a destabilizing foreign military capability that should be known by all Congressional Policy Makers."

BIDEN'S MEMORY STRUGGLES COULD IMPERIL NATIONAL SECURITY, DEFENSE EXPERTS WARN: 'NOT ONLY WEAK BUT CONFUSED'

Turner's office did not immediately respond to Fox News Digital's request for comment and more information.

White House National Security Advisor Jake Sullivan said Wednesday at the White House press briefing that earlier in the week, he reached out to the Gang of Eight to offer himself for a personal briefing on the matter. That briefing will take place Thursday.

"I am a bit surprised that Congressman Turner came out publicly today in advance of a meeting on the books for me to go sit with him alongside our intelligence and defense professionals tomorrow. That’s his choice to do that," Sullivan said.

"All I can tell you is that I’m focused on going to see him, sit with him, as well as the other House members of the Gang of Eight tomorrow, and I’m not in a position to say anything further from this podium at this time,
