WASHINGTON, Ramadan 26, 1434, Aug 4, 2013, SPA -- A senior Democratic senator said on Sunday that the U.S.-Russia relationship had become "poisonous" and urged President Barack Obama to consider moving next month's Group of 20 summit away from the Russian city of St. Petersburg, according to Reuters. Charles Schumer, the U.S. Senate's third ranking Democrat and a close Obama ally, accused Russian President Vladimir Putin of trying to antagonize the United States by granting American fugitive Edward Snowden asylum for one year. "President Putin is behaving like a schoolyard bully," Schumer said on the CBS television talk show "Face the Nation." "In my experience, I've learned unless you stand up to that bully, they ask for more and more and more." He said Obama should cancel plans to meet Putin in Moscow for a bilateral summit next month that was expected take place during the U.S. president's trip to Russia for the G20 gathering. Schumer said he also would call on Obama to "urge our allies, if it were possible," to try to move the G20 summit from St. Petersburg to another country. -- SPA 20:41 LOCAL TIME 17:41 GMT www.spa.gov.sa/1134808
