Vice President Cheney will be called as a witness in the upcoming CIA leak case.
His former top aide Lewis Libby faces trial next month. Libby is charged with perjury and obstruction in a case stemming from the leak of the identity of a CIA operative. Libby's attorney gave notice today that Cheney is on the witness list. He may be the first sitting vice president called to testify in a criminal case.
Libby's accused of lying to investigators about his conversations with reporters regarding former CIA operative Valerie Plame.
Other key witnesses expected at the trial include NBC News Washington bureau chief Tim Russert and former New York Times reporter Judith Miller.
