Late in the day Monday, the White House released what has become one of the more iconic pictures marking the killing of Osama bin Laden. The picture shows the president and his national security team in the situation room while they received updates on the operation in Pakistan.
There are lots of serious faces in the photo, but of particular note is Secretary of State Hillary Clinton, who has one hand over her mouth.
As President Obama heads to Ground Zero to honor 9/11 victims, questions remain about what Osama bin Laden's killing means for the war on terror and for U.S. troops in Afghanistan. Host Michel Martin speaks with Democratic Rep. Keith Ellison, the first Muslim member of Congress, who is renewing his call to draw down troops in Afghanistan.
