Former U.S. Sen. George Mitchell twice tried to talk to Roger Clemens about his alleged steroid use included in his report before its release, USA Today reported Monday. Mitchell twice sent letters to the Major League Baseball Players' Association requesting to speak to players who would be mentioned in his report into illegal use of steroids and other performance-enhancing drugs in Major League Baseball. The letters included the dates of their alleged steroid use and the teams they played for when they allegedly used performance enhancers. In an e-mail sent to USA Today, Mitchell said he sent letters to the players' union in the summer and in October, requesting to talk to players named in the report. In the October letter, Mitchell wrote: "During the course of any such interview, I will inform the player of the evidence of their use, including permitting him to examine and answer questions about copies of relevant checks, mailing receipts, or other documents and give him an opportunity to respond." In the first letter sent to the union, Mitchell told the newspaper that he provided detailed information regarding players who would be named in the report.
