A member of the Democratic Party, he was born in Orange, New Jersey, in 1964 and is a graduate of the United States Naval Academy. He served as a naval aviator, flew combat missions during the Gulf War, and later became a NASA astronaut, logging more than 50 days in space across four shuttle missions including as commander of the final flight of Space Shuttle Endeavour.

He sits on the Senate Armed Services Committee, the Senate Commerce, Science, and Transportation Committee, and the Senate Special Committee on Aging.
