George Mitchell called a news conference for Thursday to announce the results of his 20-month investigation into drug use in baseball. Bud Selig does not plan to attend the 2 P.M. ET news' conference at a Manhattan hotelmwhich is a few blocks from the commissioner's office. Mitchell said Wednesday he will release his report then, and it will be posted online at MLB.com shortly after that. Selig will hold his own news conference 2? hours after the one by Mitchell. Baseball reviewed a draft Tuesday at the Manhattan office of DLA Piper, the law firm that Mitchell chairs, a baseball official said, speaking on condition of anonymity because Mitchell hasn't authorized any statements. Baseball officials have said for several weeks that management would be able to examine the report on performance-enhancing drugs a few days before it is made public to make sure it does not contain confidential information that if released would violate the collective bargaining agreement between players and owners.
