The hearing, which will assess what risks UFOs pose to national security, will be chaired by Rep. Andre Carson (D-Ind.).

"Congress hasn't held a public hearing on unidentified aerial phenomena (UFOs) in over 50 years," Carson wrote on Twitter on Tuesday alongside black and white photos of what appeared to be mysterious flying objects.

"That will change next week when I lead a hearing in House Intelligence on this topic and the national security risk it poses. Americans need to know more about these unexplained occurrences."

The hearing will take place on May 17 at 10 a.m. ET and can be watched online.

Witnesses will include Under Secretary of Defense for Intelligence and Security Ronald S. Moultrie and Deputy Director of Naval Intelligence Scott W. Bray.

After the public hearing, a closed, classified hearing will follow that will focus on the Pentagon's Airborne Object Identification and Management Synchronization Group, which was established in November 2021 and replaced the U.S. Navy's Unidentified Aerial Phenomena Task Force.

That group's role is to "detect, identify, and attribute objects of interest in Special Use Airspace and to assess and mitigate any associated threats to safety of flight and national security," according to the Department of Defense.
