Chris Van Hollen is the senior United States Senator from Maryland, having served in the Senate since 2017. A member of the Democratic Party, he was born in Karachi, Pakistan, in 1959, the son of a U.S. Foreign Service officer, and grew up partly abroad before attending Swarthmore College, Johns Hopkins University's School of Advanced International Studies, and Georgetown University Law Center. Before his Senate career, he served eight terms in the House of Representatives representing Maryland's 8th Congressional District, where he became ranking member of the House Budget Committee and a leading Democratic voice on fiscal policy. He was elected to the Senate in 2016 to fill the seat vacated by retiring Senator Barbara Mikulski.
In the Senate, Van Hollen serves on the Appropriations Committee and the Budget Committee, where he has been a consistent advocate for federal investment in education, infrastructure, and healthcare. He has developed a reputation as a pragmatic legislator capable of working across the aisle on complex fiscal matters, and he chairs the Democratic Senatorial Campaign Committee during election cycles. He has been an outspoken advocate on foreign policy matters, particularly regarding U.S. support for humanitarian aid and civilian protection in conflict zones.
