The United States Senate is the upper chamber of the US Congress. Its association with the topic of Unidentified Anomalous Phenomena (UAP) dates to 1989, when journalist George Knapp first told Senator Harry Reid — then in his first term — about accounts of a crashed saucer he had gathered outside his newsroom.1
Reid, Senate majority leader at the time, was the driving force behind funding for the Advanced Aerospace Threat Identification Program (AATIP), which he requested be largely funded during his tenure in that role.2 The programme formed part of a $22 million effort Reid sponsored to investigate UFOs.3 Senior members of a defense spending subcommittee, Ted Stevens of Alaska and Daniel K. Inouye of Hawaii, supported the programme.4 None of Reid, Stevens or Inouye wanted a public debate on the Senate floor about the funding.5
At a Senate hearing on 2023-07-26, David Charles Grusch said his own PPD-19 whistleblower reporting process complaint faced problems, because there was no smooth way for the intelligence community’s Inspector General to route such information to committees beyond the intelligence committees, despite his request to send it to the Armed Services Committees of the US House of Representatives and Senate, on Title 10 grounds.6 According to Glenn Grothman, Sean Kirkpatrick, director of the All-domain Anomaly Resolution Office (AARO), testified before the Senate that his unit had found no evidence of extraterrestrial activity.7 Marco Rubio said that some of his Senate colleagues are very interested in the topic of UAP, while others react dismissively when it is raised.8 David Fravor said he had spoken to multiple senators who told him that, prior to 2017, mentioning UAP would have gotten someone laughed off Capitol Hill.9
During the same hearing, the Senate was taking up an amendment to a defense authorization bill that would create a commission with broad declassification authority.10 Legislative efforts on UAP disclosure continued into 2024, when the Unidentified Aerial Phenomena (UAP) Disclosure Act was pushed back again, this time by Senator Mitch McConnell.11
A forum on UAP was held in the Kennedy Caucus Room of the Senate,12 taking place in June 2026.13
