This newly-discovered home movie of the fateful Kennedy motorcade was recently donated to The Sixth Floor Museum at Dealey Plaza. The photographer, George Jefferies, filmed President and Mrs. Kennedy on Main Street at Lamar in downtown Dallas less than 90 seconds before the assassination. Secret Service Agent Clint Hill, assigned to protect Jackie Kennedy, can be seen riding on the left rear bumper.
