According to a 1998 statute, former or current U.S. presidents are eligible for burial at historic Arlington National Cemetery regardless of whether or not they served in the military.
Two U.S. presidents, William Howard Taft and John F. Kennedy, are currently interred at Arlington. JFK served in the Navy. Taft served as Secretary of War, but did not serve in the military. Most presidents have chosen to be buried in their home states.
In June 2020, Sen. Tammy Duckworth introduced a bill to block presidents and vice presidents without a history of military service from interment at Arlington. The bill would not affect anyone already interred, and is intended to preserve limited remaining space. An expansion adding room for 60,000 more graves has been approved. About 400,000 veterans and dependents have been buried there to date.
