President Obama used Defense Secretary Robert Gates on Tuesday for a stealth attack on Mitt Romney, a leading Republican presidential contender in 2012.
Obama dispatched Gates to meet Senate Republicans to discuss a U.S.-Russia nuclear arms treaty and other national security issues.
Romney, widely seen as interested in another bid for the Oval Office, fired a shot at Obama last week in an op-ed that urged Republicans to oppose a new Strategic Arms Reduction Treaty (START) with Russia.
