The prosecutor has been investigating charges that the Bush administration leaked Plame's name to several journalists in retaliation for an article that her husband, former envoy Joseph C. Wilson IV, wrote in the New York Times that accused the administration of using faulty intelligence in deciding to wage war in Iraq....
....Over the weekend, a lawyer for Karl Rove, Bush's deputy chief of staff, acknowledged that Rove had spoken with (reporter Matthew Cooper) in the days before the Novak article appeared, but denied that Rove had identified Plame or broken the law.
