On November 1, 1950, Griselio Torresola and Oscar Collazo attempt to assassinate President Harry S. Truman at the Blair House in Washington, D.C. Truman escaped unscathed.
In the autumn of 1950, the White House was being renovated and President Truman and his family were living in the nearby Blair House on Pennsylvania Avenue. On the afternoon of November 1, Truman and his wife were upstairs when they heard a commotion—and gunshots—coming from the front steps of the house. Indeed, the pair of would-be assassins had strolled up to the front door of Blair House and opened fire. They never made it past the entry steps, however, due to the quick reaction of police officers and guards. Secret Service Agent Leslie Coffelt was mortally wounded in the ensuing melee, but not before he managed to kill Torresola.
