"My credibility is not on the line. The international community's credibility is on the line," Obama told a news conference in Stockholm. "And America and Congress' credibility is on the line." The President travels to the G-20 meeting in St. Petersburg on Thursday. Russian President Vladimir Putin has opposed the tentative plans for U.S. attack.
