"We have also, I think, been reminded about how important it is to try to deal with extremism of any kind, especially when it uses violence to try to achieve political and ideological goals," Clinton said. "So I'm one who thinks that there are lessons still to be learned from what happened to us on 9/11 that we should be very aware of during this time in our country and the world's history."

Clinton recalled what it was like to be a senator from New York at the time of the attacks and how Republicans and Democrats were able to rally behind President George W. Bush in a way the country hasn’t seen since.
