White House deputy chief of staff Karl Rove will testify tomorrow morning for a fourth time before the federal grand jury investigating the Valerie Plame matter, according to sources close to the investigation.
Rove will appear voluntarily, but during tomorrow's session, Rove will be pressed about issues as to why his accounts to the FBI and grand jury have changed, or evolved, over time. He will also be questioned regarding contacts with other senior administration officials, such as then-deputy National Security advisor Stephen J. Hadley and I. Lewis Libby, the chief of staff to Vice President Dick Cheney in the critical week before the publication of columnist Robert Novak's column on July 14, 2003, which outed Plame as a covert CIA operative.
Rove is also likely to be asked more detailed questions about his conversation with Time magazine Matthew Cooper on July 11, 2003, in which Cooper himself has testified to the grand jury that Rove had told him that Valerie Plame was employed by the CIA, and had played a role in having her husband, ambassador Joseph C. Wilson IV, selected to go on his controversial fact-finding mission on behalf of the CIA. Rove's previous grand jury appearances had occurred prior to Cooper's own testimony to the grand jury.
