Murray Waas says Novak and Rove may have collaborated to obstruct and mislead the Fitzgerald enquiry:
On September 29, 2003, three days after it became known that the CIA had asked the Justice Department to investigate who leaked the name of covert CIA officer Valerie Plame, columnist Robert Novak telephoned White House senior adviser Karl Rove to assure Rove that he would protect him from being harmed by the investigation, according to people with firsthand knowledge of the federal grand jury testimony of both men. . . .There are also indications that Cheney may testify at the Libby enquiry:
Rove and Novak, investigators suspect, might have devised a cover story to protect Rove because the grand jury testimony of both men appears to support Rove's contentions about how he learned about Plame.
Fitzgerald said Cheney's "state of mind" is "directly relevant" to whether I. Lewis "Scooter" Libby, the vice president's former top aide, lied to FBI agents and a federal grand jury about how he learned about CIA officer Valerie Plame's identity and what he subsequently told reporters.Much more at TPM muckraker.
Libby "shared the interests of his superior and was subject to his direction," the prosecutor wrote. "Therefore, the state of mind of the vice president as communicated to (the) defendant is directly relevant to the issue of whether (the) defendant knowingly made false statements to federal agents and the grand jury regarding when and how he learned about (Plame's) employment and what he said to reporters regarding this issue."
