Barry Bonds’ lawyer told the Associated Press today (March 23) that he plans to file a lawsuit over the book “Game of Shadows,” which alleges the Giants slugger used steroids. Attorney Michael Rains sent a letter to an agent for the authors of “Game of Shadows,” alerting them of his plans to sue Chronicle reporters Mark Fainaru-Wada and Lance Williams, publisher Gotham Books, the Chronicle and Sports Illustrated, which published excerpts earlier this month. Rains will ask a judge Friday (March 24) to issue a temporary restraining order forfeiting all profits from publication and distribution, according to the letter. Rains will ask a federal judge to initiate contempt proceedings “for the use of illegally obtained” grand jury transcripts the authors used in writing the book. During those proceedings, the reporters might be forced to reveal who gave them the transcripts. [Chron gets a phone message from lawyer, warning of suit]
