Photo of the day: Obama signs military aid bill to Israel

President Barack Obama shakes hands with Richard Stone, chairman of the Conference of Presidents of Major American Jewish Organizations, after signing the United States-Israel Enhanced Security Cooperation Act. The measure won approval from Congress July 17. Under the bill, the U.S. will authorize $70 million in aid to Israel to expand its short-range rocket defense known as "Iron Dome." The bill's signing coincides with Republican presidential candidate Mitt Romney's visit in Israel this weekend.
