There's no such thing as royalty in the United States, but if anyone has ever come close to that level, it's the Kennedy family. For 64 years, Washington had at least one Kennedy in public office. Descended from Irish Catholics who fled the potato famine, the family has a strong tradition in the Democratic party, the most prominent member being President John F. Kennedy. In addition to fame and political power, the Kennedy clan has had more than its fair share of tragedy—several members of the family have died in accidents and assassinations, in what's been called the "Kennedy curse."
Trump allowed the immediate release of 2,800 records by the National Archives. However thousands of other papers on JFK’s untimely death were withheld for “national security, law enforcement, and foreign affairs concerns.”
