Zero Fail: The Rise and Fall of the Secret Service by Carol Leonnig:
At the time of the shooting, President Obama had been sitting courtside on the USS Carl Vinson warship in Coronado Bay, watching the fourth quarter of a basketball game between the University of North Carolina and Michigan State University on the flight deck. He was getting ready to be interviewed by ESPN at 9:05 P.M.
Not long after, the Carolina Tarheels were celebrating beating the Michigan State Spartans, 67-55. The president had finished his interview. He congratulated the players on a great game and chatted briefly with the basketball legend Magic Johnson. Forty-five minutes after the shooting, Barack and Michelle Obama climbed aboard Air Force One, bound for a trade summit in Honolulu. Director Sullivan was traveling with the president. Mickey Nelson, Sullivan’s assistant director for protective operations, called the director to let him know there had been a shooting near Crown. Everything was okay, Nelson emphasized. “It doesn’t look like there’s any connection to the White House,” he said. The First Couple was still unaware that a man had taken several shots at their residence while one of their daughters was at home and another was en route.
