Three more U.S. senators received a classified Pentagon briefing on Wednesday about a series of reported encounters by the Navy with unidentified aircraft, according to congressional and military officials — part of a growing number of requests from members of key oversight committees.

One of them was Sen. Mark Warner (D-Va.), the vice chairman of the Senate Intelligence Committee, whose office confirmed the briefing to POLITICO.


“If naval pilots are running into unexplained interference in the air, that’s a safety concern Senator Warner believes we need to get to the bottom of,” his spokesperson, Rachel Cohen, said in a statement.

The interest in “unidentified aerial phenomenon” has grown since revelations in late 2017 that the Pentagon had set up a program to study the issue at the request of then-Sen. Harry Reid (D-Nev.). Officials interviewed multiple current and former sailors and aviators who claim to have encountered highly advanced aircraft that appeared to defy the laws of aerodynamics when they intruded on protected military airspace — some of which were captured on video and made public.

The Navy has played a prominent role in light of the testimony of F/A-18 pilots and other personnel operating with the USS Nimitz aircraft carrier battle group off California in 2004 and the USS Theodore Roosevelt in the Atlantic in 2015 and 2016.

The growing congressional interest is credited for playing a major role in the service’s recent decision to update the procedures for reporting such unexplained sightings, which POLITICO first reported in April.


“Navy officials did indeed meet with interested congressional members and staffers on Wednesday to provide a classified brief on efforts to understand and identify these threats to the safety and security of our aviators," spokesman Lt. Cmdr. Daniel Day said in a statement.

He said "follow-up discussions with other interested staffers" were also scheduled for Thursday. "Navy officials will continue to keep interested congressional members and staff informed. Given the classified nature of these discussions, we will not comment on the specific information provided in these Hill briefings.”

The briefings come several days after President Donald Trump told ABC News that he, too, had been briefed on the reports. “I did have one very brief meeting on it,” he said. “But people are saying they’re seeing UFOs. Do I believe it? Not particularly.”

But several current and former officials with direct knowledge describe the Capitol Hill briefing as the latest for members of Congress and their staff representing the Intelligence, Armed Services and Defense Appropriations panels.

“There are people coming out of the woodwork,” said one former government official who has participated in some of the meetings.


A current intelligence official added: “More requests for briefings are coming in.”

The sessions have been organized by the Navy but have also included staff from the under secretary of Defense for Intelligence, the sources said. Both were not authorized to talk publicly about the briefings.

Advocates for giving the mystery greater attention say they hope Congress will take more formal steps, such as requiring the Department of Defense to collect and complete a detailed analysis of data collected by satellites and other means of unidentified craft intruding into military airspace or operating under the sea.
