The Attending Physician of the United States Congress is the physician responsible for the medical welfare of the members of the United States Congress (the 435 Representatives, five delegates, Resident Commissioner of Puerto Rico, and 100 Senators) and the nine justices of the Supreme Court of the United States.
The Attending Physician is also tasked with emergency care for thousands of staff, security personnel and dignitaries, and implementation of the environmental health, public health, and occupational health programs of the Capitol Hill region (which includes the Capitol, the congressional office buildings, and the Supreme Court building). The Attending Physician is instrumental in security planning and works with the Architect of the Capitol, Senate Sergeant at Arms, House Sergeant at Arms, United States Capitol Police, and other congressional officials to ensure medical support during contingency operations.
