In the margins of the op-ed, Cheney jotted out a series of questions that seemed to challenge many of Wilson’s assertions as well as the legitimacy of his CIA-sponsored trip to Africa: “Have they done this sort of thing before? Send an Amb. [sic] to answer a question? Do we ordinarily send people out pro bono to work for us? Or did his wife send him on a junket?”

The role of Vice President Dick Cheney in the criminal case stemming from the outing of White House critic Joseph Wilson’s CIA wife is likely to get fresh attention as a result of newly disclosed notes showing that Cheney personally asked whether Wilson had been sent by his wife on a “junket” to Africa. Cheney’s notes, written on the margins of a July 6, 2003 New York Times op-ed column by former ambassador Joseph Wilson, were included as part of a filing Friday night by prosecutor Patrick Fitzgerald in the perjury and obstruction case against ex-Cheney chief of staff I. Lewis “Scooter” Libby. The notes, Fitzgerald said in his filing, show that Cheney and Libby were “acutely focused” on the Wilson column and on rebutting his criticisms of the White House’s handling of pre-Iraq war intelligence. In the column, which created a firestorm after its publication, Wilson wrote that he had been dispatched by the CIA without pay to Niger in February 2002 to investigate an intelligence report that Iraq was seeking uranium from the African country for a nuclear bomb. Wilson said he was told Cheney had asked about the intelligence, but the White House subsequently ignored his findings debunking the Niger claims.

It is extremely rare, if not unprecedented, for Cheney’s own notes to be made public. The notes—apparently obtained as a result of a grand jury subpoena—would appear to make Cheney an even more central witness than had been previously thought in the criminal probe. Fitzgerald’s prosecution has created continued problems for the White House. Karl Rove, the President Bush’s chief political adviser, recently made his fifth grand jury appearance in the case and remains under scrutiny while Fitzgerald weighs whether to file criminal charges against him. For now, Libby is the only figure charged in the case.
