At 9:03 AM on 11 September 2001, the second airplane hit the South Tower of the World Trade Center. President Bush was in Florida, at the Emma T. Booker Elementary School, listening to children read. Chief of Staff Andrew Card came over and whispered in Bush's ear, "A second plane hit the second tower. America is under attack."
What did the Commander in Chief do? Nothing. He sat there. He sat for well over 5 minutes, doing nothing while 3,000 people were dying and the attacks were still in progress.
