Fehr said he was aware of the statements, and "we have always cooperated with congressional requests to appear." Fehr and Selig were part of the March 17, 2005, congressional hearing that pushed both sides toward a stronger policy.
Clemens' attorney, Rusty Hardin, issued the following statement: "Roger has been repeatedly tested for these substances, and he has never tested positive. There has never been one shred of tangible evidence that he ever used these substances, and yet he is being slandered today."
Pettitte's agent, Randy Hendricks, said he advised his client, as an active major leaguer, not to make public comment until he has spoken with the union and other advisers.
Whether any of the players will face punishment from the league is undetermined. Despite Mitchell's assertion that they shouldn't, Selig said each would be reviewed on a "case-by-case basis."
If disciplined, Fehr said, his members would be given the choice to file an appeal.
Among the DLA Piper lawyers that helped Mitchell investigate and compile the report were Baltimore attorney Charles Scheeler and New York attorney John Clarke, a 1983 Gilman School graduate.
