ROUGH CUT (NO REPORTER NARRATION) Democratic presidential candidate Bernie Sanders remembered U.S. troops and veterans at the San Francisco National Cemetery on Memorial Day Monday. He took part in this year's Presidio Memorial Day Commemoration, which included former soldiers in uniform, and remembers U.S. forces that took part in the Vietnam and Korean wars. Sanders, a U.S. senator from Vermont, is still locked in a tight primary battle against Democratic front-runner Hillary Clinton, while Donald Trump has clinched the required number of delegates to become the presumptive Republican nominee.
