Obama Visits Ground Zero to Mark the Death of bin Laden

President Obama today laid a wreath at Ground Zero and met with the families of 9/11 victims. After lunching with firefighters at Engine Company 54, which he called "symbolic" of the sacrifices made almost ten years ago, he spoke about the killing of Osama bin Laden. The President said that bin Laden's death sent a message around the world that the US would neither forget nor stop until fulfilling our commitment to make sure that justice was done.
