Office of the Attending Physician, U.S. Congress: Background Information and Response to Public Health Emergencies [May 14, 2020] [open pdf - 635KB]
From the Document: "The Office of the Attending Physician (OAP) was established in 1928, after the House agreed to a resolution on December 5, 1928, requesting the Secretary of the Navy detail a medical officer to the House (H.Res. 253, 70th Congress). On April 7, 1930, the Senate agreed to a concurrent resolution (S.Con.Res. 14, 71st Congress) extending the services of the Attending Physician to both chambers. Although the House never considered the concurrent resolution, the OAP began serving both the House and the Senate at that time. Since the initial appointment in 1928, the Attending Physician, and other medical assistants in the office, have continued to be assigned from the Department of the Navy."
