From MLB.com:

Commissioner Bud Selig said on Wednesday that he wants Jason Giambi to meet with former U.S. Sen. George Mitchell during the next two weeks before determining whether to discipline the Yankees first baseman regarding statements about his alleged steroid use, which Giambi made to a newspaper last month.

"It is in the best interests of baseball for everyone, including players, to cooperate with Sen. Mitchell in his investigation so that Sen. Mitchell can provide me with a complete, thorough report," Selig said.

From Peter Abraham:

"If this is the precedent that's going to be set - that if you do an interview and talk out against Major League Baseball and we don't like your answers, we're going to punish you even worse - I think it's a joke," [Mike Myers] said.

Said Yankees player rep Mike Mussina: "Bud thinks he can do whatever he wants, so we'll find out."

Myers said the MLBPA would fight any discipline Selig tries to impose on Giambi. Steroids were not banned by baseball until 2005 and there is no language in the collective bargaining agreement to discipline players for use prior to that.
