Anti-war group Code Pink marked President Barack Obama's birthday Sunday with a knock against U.S. drone policy.
Code Pink, which regularly protested war on terror policies under President George W. Bush, has been sharply critical of Obama as well. In May, Code Pink co-founder Medea Benjamin interrupted Obama repeatedly during speech on national security issues.
