President Obama invoked the Libya attacks during a campaign stop in Golden, Colorado, on Thursday, vowing there would be repercussions for those responsible.

President Obama: “We are going to bring those who killed our fellow Americans to justice. I want people around the world to hear me. To all those who would do us harm: No act of terror will go unpunished. They will not dim the light of the values that we proudly present to the rest of the world. No act of violence shakes the resolve of the United States of America.”
