It was Waxman's Feb. 27 memo that outlined the reasons the panel referred Clemens to the Justice Department, summarizing "seven sets of assertions made by Mr. Clemens in his testimony that appear to be contradicted by other evidence before the committee or implausible."

Those areas involve Clemens' testimony that he has "never taken steroids or HGH"; that McNamee injected him with the painkiller lidocaine; that team trainers gave him pain injections; that he received many vitamin B-12 injections; that he never discussed HGH with McNamee; that he was not at then-teammate Jose Canseco's home from June 8-10, 1998, when their Toronto Blue Jays played a series at the Florida Marlins; and that he was "never told" about baseball investigator George Mitchell's request to speak to Clemens before issuing the report containing McNamee's allegations.

Clemens last played in the major leagues in 2007, with the New York Yankees.
