NEW YORK (AP) — First lady Michelle Obama urged Hollywood to give a more accurate portrayal of veterans and defended the Oscar-nominated "American Sniper," which has received criticism for its depiction of war. Bradley Cooper, who is nominated for best actor for his portrayal of the late Navy SEAL sniper Chris Kyle, joined Obama and media heavyweights in Washington, D.C., on Friday to launch "6 Certified" with representatives from Warner Bros., National Geographic Channels and the Producers Guild of America.
