Criminal indictments are expected as early as today in the case surrounding the outing of CIA operative Valerie Plame. Plame is the wife of former ambassador Joseph Wilson, who publicly challenged White House claims that Iraq had attempted to purchase yellowcake from Niger. Prosecutors have stepped up their focus on President Bush’s chief of staff Karl Rove. Investigators with the office of Special Prosecutor Patrick Fitzgerald met with associates of Rove yesterday. Meanwhile, the Bush administration sidestepped questions about the role played by Vice President Dick Cheney. On Tuesday the New York Times reported that Cheney had revealed Plame’s name to his chief of staff Scooter Libby.
