In his first in-depth interview since leaving office, President George W. Bush spoke with NBC's Matt Lauer in an hour-long program Monday night. From 9/11 to the invasion of Iraq to Hurricane Katrina to the Wall Street meltdown, Bush reflected on the major decisions of his presidency, as discussed in his new memoir "Decision Points." Though he expressed remorse about a number of moments during his reign, he stood behind his most controversial actions.
