Katie Couric asked Senator Clinton about "the new aggressive tone" her campaign is using against other candidates. Clinton responded, "After you have been attacked as often as I have by several of my opponents, you can't just absorb it. You have to respond."

Clinton told Couric that she doesn't even consider the possibility that she might not be the Democratic nominee. Clinton said, "It will be me."
