On October 1, 2004, federal Judge Thomas F. Hogan found Miller in contempt of court for refusing to appear before a federal grand jury, which was investigating who had leaked to reporters the fact that Valerie Plame was a CIA operative. Miller did not write an article about the subject at the time of the leak, but others did, notably Robert Novak, spurring the investigation. Judge Hogan sentenced her to 18 months in jail, but stayed the sentence while her appeal proceeded. On February 15, 2005, the United States Court of Appeals for the District of Columbia Circuit unanimously upheld Judge Hogan's ruling. On June 17, 2005, the US Supreme Court declined to hear the case. On July 6, 2005, Judge Hogan ordered Miller to serve her sentence at "a suitable jail within the metropolitan area of the District of Columbia". She was taken to Alexandria City Jail on July 7, 2005.
