Clinton insists her vote would not support military strikes and instead was a vote for stepped-up diplomacy. Last week, the Bush administration declared the Revolutionary Guard a proliferator of weapons of mass destruction and announced new sanctions meant to isolate Iran. The Iranian government contends its nuclear program is aimed only toward providing nuclear power. Clinton and 29 other senators wrote to Bush Thursday to tell him he has no congressional authority for war with Iran. The four Democratic senators running for the White House split over whether to sign the letter. Chris Dodd of Connecticut added his support, while Obama and Joe Biden of Delaware declined. The letter accuses Bush of “provocative statements and actions stemming from your administration with respect to possible U.S. military action in Iran.” WASHINGTON – Democrat Barack Obama is offering a Senate resolution that says President Bush does not have authority to use military force against Iran, the latest move in a debate with presidential rival Hillary Rodham Clinton about how to respond to that country’s nuclear ambitions. Clinton’s campaign accused Obama of playing politics instead of taking a leadership role from the outset. Obama spokesman Bill Burton said the Illinois senator will introduce the measure Friday in an effort to “nullify the vote the Senate took to give the president the benefit of the doubt on Iran.” Burton was referring to an amendment sponsored by Sens. Jon Kyl, R-Ariz., and Joe Lieberman, an independent from Connecticut, that passed 76-22 on Sept. 26 and designates Iran’s Revolutionary Guard as a terrorist organization.
