Special Report host Bret Baier shared a poignant and intimate interview with Former First Lady Laura Bush and President George W. Bush. Laura began by giving Bret a tour of the George W. Bush Presidential Library before she and her husband, former president George W. Bush, sat down for the one-on-one. 

A key installation in the library depicts the timeline of September 11, 2001 - a pivotal moment in Bush's presidency. Bret asked the former commander in chief for his thoughts on the recent Boston attack.

"You know, it did cause me to think back to our time in the White House," he said, adding that the same lesson could be extracted from both tragic attacks: evil exists.

"There are people willing to murder innocent people, and therefore the country really cannot ever let its guard down, sadly cannot let its guard down."
