I'll look that up for you. Your U.S. representative in Massachusetts's 4th congressional district (MA-04) is **Jake Auchincloss**. Jacob Daniel Auchincloss is an American politician, businessman, and Marine Corps officer serving as the U.S. representative for Massachusetts's 4th congressional district since 2021. He is a member of the Democratic Party and previously served as a member of the Newton City Council from 2015 to 2021. In the most recent election, incumbent Jake Auchincloss won the general election for U.S. House Massachusetts District 4 on November 5, 2024, after advancing from the Democratic primary on September 3, 2024.
