President Donald Trump said his administration on Tuesday will release all the government's files on the assassination of President John F. Kennedy.

But as the motorcade was finishing its parade route downtown, shots rang out from the Texas School Book Depository building. Police arrested 24-year-old Lee Harvey Oswald, who had positioned himself from a sniper’s perch on the sixth floor. Two days later, nightclub owner Jack Ruby fatally shot Oswald during a jail transfer.
