Finally tonight, an historic moment today at the White House, as President Obama conferred the Medal of Honor, the nation's highest medal of valor, on 25-year-old Staff Sgt. Salvatore Giunta. Giunta became the first living soldier to receive the medal since 1976. The president described Giunta's heroic actions when his unit in Afghanistan was attacked at night in October 2007: After two Taliban fighters captured his comrade, Sgt. Josh Brennan, Giunta gave pursuit, killing one Taliban and wounding the other. He then provided first aid to Brennan, although he could not save him. Giunta was shot twice in the attack. Today he had this to say: "Incredible time but it's also kind of a bittersweet time. … I lost two good friends of mine… and although this is so positive, I would give this back in a second to have my friends with me right now."
