Maybe [Donald Trump] is just never dealt with somebody who's not particularly impressed by his carrying on, but I'm not. So I'm going to stay focused on what's at stake in this election.

It is, from my perspective, less important today looking backwards as to why these militants decided they did it than to find them and bring them to justice, and then maybe we'll figure out what was going on in the meantime.

You can go into neighborhoods in the United States where people dress a certain way because they don't want to be out of touch, where boys wear pants down to their knees, which nobody has compelled them to do but they pick up the cultural norms, or where girls are improperly dressed by my eyes, but that's what they see in the media.

The United States has, unfortunately, been victimized by terrorism going back decades.

I think we've got to do more to stop foreign fighters, foreign funding and take ISIS on online, as well as doing everything necessary to keep us safe at home.

I think that we have to look at ISIS as the leading threat of an international terror network. It cannot be contained, it must be defeated.

Military activities (are) not a role for the United States. There needs to be a number of steps that Maliki and his government must take to demonstrate that he is committed to an inclusive Iraq, something he has not done up to date.
