Who represents howard county in the House of Representatives?

As of my last update, Howard County, Maryland, is represented in the U.S. House of Representatives by Rep. David Trone, a member of the Democratic Party. He has served since January 2019, representing Maryland's 6th congressional district, which includes parts of Howard County. However, it’s always a good idea to verify with current sources, as congressional representation can change due to elections or redistricting.
