A group of top White House officials including President Bush’s senior advisor Karl Rove, Vice President Dick Cheney’s chief of staff Lewis Scooter Libby, White House press secretary Scott McClellan, Cheney’s former counselor Mary Matalin and White House communications director Dan Bartlett have all been questioned by a federal grand jury that is trying to uncover who revealed the name of an undercover CIA agent last year. According to the Washington Post, the grand jury has obtained phone logs that show several White House officials talked to conservative columnist Robert Novak shortly before he published his July 14 that outed Valerie Plame as an agent. Plame is the wife of former Joseph Wilson who was in the news at the time for criticizing President Bush’s invasion of Iraq. Sources told the Post the grand jury had also seen internal White House emails criticizing Wilson. The Intelligence Identities Protection Act makes it a felony to disclose a covert agent’s identity if the person making the disclosure knew the covert status of the employee and revealed it intentionally.
