In his latest Plame filing, Patrick Fitzgerald states why it may be necessary to call Vice President Dick Cheney to the witness stand in Scooter Libby's trial:

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."

Am I wrong, or is Fitzgerald stating that Cheney's testimony will demonstrate that the VP wanted Plame outed, and Libby lied to the grand jury about outing Plame in order to take the heat off his boss?
