Biden warns ISIS

Biden says the U.S. is grieving the deaths of Foley and Sotloff and will bring ISIS to justice:

They should know we will follow them to the gates of hell until they are brought to justice. Because hell is where they will reside. Hell is where they will reside.

He says America will not be intimidated by brutal acts like the beheading by ISIS of the two journalists:

We came back after 9/11. We dusted ourselves off and we made sure that Osama bin Laden would never, ever again threaten the American people. We came back after Boston strong, blaming no one but resolving to be certain that this didn’t happen again. As a nation, we’re united, and when people harm Americans, we don’t retreat. We don’t forget.
