President-elect Barack Obama wears a bracelet engraved with the name of Sgt. Ryan David Jopek as he addresses reporters at news conference announcing New Mexico Gov. Bill Richardson as his secretary of commerce in Chicago on December 3, 2008. Jopek was killed in Iraq by a roadside bomb on August 2, 2006, and the bracelet was given to Obama by Jopek's mother while he was on the campaign trail. (UPI Photo/Brian Kersey)
