Jake Auchincloss

Jacob Daniel Auchincloss (born January 29, 1988) is an American politician and former Marine Corps officer serving as the U.S. representative for Massachusetts's 4th congressional district since January 2021. A member of the Democratic Party, he represents a district encompassing parts of Middlesex, Norfolk, and Worcester counties, including communities such as Newton, where he was raised, and has been reelected twice.

Born in Boston to a surgeon father and scientist mother, Auchincloss graduated from Newton North High School in 2006, earned an A.B. from Harvard University in 2010, and obtained an M.B.A. from the Massachusetts Institute of Technology in 2016. Following college, he commissioned as an infantry officer in the United States Marine Corps, serving from 2010 to 2015; during this period, he commanded a platoon in combat deployment to Helmand Province, Afghanistan, in 2012 and led a reconnaissance unit in Panama in 2014, attaining the rank of captain before transitioning to the reserves as a major. After military service, he worked in business while entering local politics, winning election to the Newton City Council in 2015 and serving until 2020.

Auchincloss entered federal politics by defeating ten Democratic primary opponents in 2020 to succeed retiring Representative Joe Kennedy III, securing the general election in the solidly Democratic district and focusing his legislative efforts on innovation, infrastructure, and national security as a member of committees including Transportation and Infrastructure and the Select Committee on Strategic Competition between the U.S. and China. His military background and emphasis on pragmatic problem-solving distinguish his approach amid partisan divides, though he has faced criticism from progressive factions for positions on foreign policy and fiscal issues.
