Clint Hill, the Secret Service agent who tried to shield the Kennedys, dies at 93

President John F. Kennedy slumps down in the back seat of the presidential limousine as it speeds along Elm Street toward the Stemmons Freeway overpass in Dallas, Texas, after being fatally shot, Nov. 22, 1963. First lady Jacqueline Kennedy leans over the president as Secret Service Agent Clint Hill pushes her back to her seat.

Hill received Secret Service awards and was promoted for his actions that day, but for decades blamed himself for Kennedy's death, saying he would gladly have given his life to save the president.
