Lance Williams and Mark Fainaru-Wada co-authored the book Game of Shadows while they were reporters for the San Francisco Chronicle. For their investigative work in the field of steroids, Williams and Fainaru-Wada were given the 2004 George Polk Award. In the course of their investigative research, Williams and Fainaru-Wada were the first to report that: track star Marion Jones purportedly received illegal drugs from the steroid supplier BALCO world record-holder Tim Montgomery testified before a federal grand jury that he had used steroids baseball slugger Jason Giambi testified that he had used steroids On May 5, 2006, Fainaru-Wada and Williams were subpoenaed to testify before a federal grand jury about how they obtained leaked grand jury testimony. On May 31, the authors urged United States District Judge Martin Jenkins of San Francisco to excuse them from testifying. This appeal was supported by affidavits from Washington Post reporters Carl Bernstein and Mark Corallo, a former press secretary to former Attorney General John Ashcroft, but was denied on August 15, 2006. On September 21, 2006, after refusing to comply with the subpoena, the journalists were sentenced to 18 months in prison for contempt of court.
