Senator King is a member of the Armed Services Committee, the Select Committee on Intelligence, the Committee on Energy and Natural Resources, and the Committee on Veterans’ Affairs. He has made it a priority not to miss Committee hearings, earning him praise from his colleagues and the reputation as a workhorse in the Senate. The late Senator John McCain (R-Ariz.), who served as Armed Services Chairman, once called Senator King “one of the most serious and hard-working members” of the Committee.
