Andrew Card was President George W. Bush's Chief of Staff on the morning of September 11, 2001. He and the President had been visiting the Emma T. Booker Elementary School in Sarasota, Florida, when he received news that a plan had crashed in to the World Trade Center. At first he thought it was an awful accident, but when the second plane hit he knew he had to tell the president the nation had been attacked.

Card, now the president of Franklin Pierce University, joined Boston Public Radio with Jim Braude and Margery Eagan to reflect on that day.
