From a story on politico.com by Marianne Levine, Daniella Diaz, and Burgess Everett headlined “The truth is out there: UFO fever grips Congress”:

Senators left a classified briefing with at least one question answered about the three unidentified flying objects that the military shot down over the weekend: They weren’t aliens.

That’s about where the certainty ends.

Members of both parties entered the briefing room with Biden administration officials wanting more information about the origin of the unidentified objects. They left the room reiterating calls for more transparency from the White House.
