Cheney's office raised the questions that spurred the CIA to send former U.S. Ambassador to Iraq, Joe Wilson, to Iraq. Cheney did not order Wilson's trip, but the desire to answer some questions about potential deals between Iraq and Niger led the CIA to send Wilson.
Republicans have tried to provide some political cover for Rove by claiming Rove was trying to warn Time Magazine reporter, Matthew Cooper, away from reporting that Cheney ordered the trip. They claim Wilson said Cheney sent him even though neither Wilson's op-ed nor any of his interviews mention it.
