Michael Gallagher is an American former Marine Corps intelligence officer and Republican politician who represented Wisconsin in the U.S. House from 2017 until 2024. He earned advanced degrees in security studies, served on the Armed Services and Intelligence committees, and chaired the House select committee focused on strategic competition with China. After Congress he became head of defense at Palantir and continued in national-security roles.

Gallagher served as a Marine intelligence officer, including deployments connected to Iraq, and completed advanced academic work on international security before entering Congress. In the House he became known for defense policy and later chaired the select committee on strategic competition with China. Leaving elected office did not end that career trajectory; he moved into defense technology and strategy. His UAP questions fit a broader professional concern with classified capability, adversary surprise, and whether oversight institutions understand what contractors and agencies are doing.

Gallagher was one of the sharper questioners at the House’s May 2022 public UAP hearing. He asked Pentagon witnesses about the Malmstrom missile incident and entered the Wilson–Davis document into the congressional record. Those actions did not authenticate every allegation in the materials, but they forced officials to address specific historical claims rather than speak only in generalities.

Gallagher connects congressional hearings, military intelligence, and defense technology. His role demonstrates how lawmakers can use public questioning to preserve disputed documents and expose gaps in agency preparation. He is not a firsthand UAP witness, and his later private-sector position should not be treated as proof of access to anomalous technology. His importance is institutional and on the record.
