Michael John Gallagher, commonly known as Mike Gallagher, is an American politician and former U.S. Representative for Wisconsin's 8th congressional district from 2017 to 2024. A Republican, he served on the House Armed Services Committee, the House Permanent Select Committee on Intelligence, and as chair of the House Select Committee on the Chinese Communist Party. Known for his bipartisan approach to national security issues, Gallagher previously served as a U.S. Marine Corps intelligence officer from 2006 to 2013, with deployments to Iraq during the Iraq War. Before entering Congress, he worked as a staff member on the U.S. Senate Foreign Relations Committee under Senator John McCain, focusing on international relations and security policy. Gallagher resigned from Congress in April 2024 to join the tech sector, specifically the defense tech firm Eleos Energy, where he continues to influence policy through advisory roles. His career reflects a commitment to countering foreign threats, particularly from China and Russia, while advocating for technology and cybersecurity reforms. He has been involved in legislation addressing supply chain vulnerabilities and human rights abuses in China. Born and raised in Wisconsin, Gallagher's Midwestern roots and family background in public service influenced his political path. He is known for his pragmatic conservatism and willingness to work across the aisle, earning respect from both parties despite occasional controversies over his votes against party-line positions, such as on foreign aid.
