Miller was involved in the Plame Affair, where Valerie Plame was outed as a Central Intelligence Agency (CIA) spy by Richard Armitage after her husband published a "New York Times" op-ed casting doubts on claims that Saddam Hussein sought to purchase uranium from Africa. Miller spent 85 days in jail for refusing to reveal that her source in the Plame Affair was Scooter Libby. Later, she contributed to the conservative Fox News Channel and "Newsmax", and was a fellow at the conservative Manhattan Institute.
