Main article: State funerals in the United States
In the United States, state funerals are held in the nation's capital, Washington, D.C., and involve military spectacle, ceremonial pomp, and religious observance. As the highest possible honor bestowed upon a person posthumously, state funerals are an entitlement offered to a sitting or former President of the United States, a President-elect, as well as other people designated by the President.[17][18] Administered by the Military District of Washington (MDW), state funerals are greatly influenced by protocol, steeped in tradition, and rich in history. However, the overall planning as well as the decision to hold a state funeral, is largely determined by the President before his death and the First Family.[19]
