President Obama’s comments were echoed more forcefully by Vice President Joe Biden, who told a crowd that the United States will follow ISIS “to the gates of hell.”

Vice President Joe Biden: “As a nation, we’re united. And when people harm Americans, we don’t retreat, we don’t forget. We take care of those who are grieving, and when that’s finished, 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.”
