Talks about Roger Clemens’ lack of credibility in the light of the allegations against him could turn against McNamee this time, after the 109-page report issued by the Republicans on the House Committee on Oversight and Government Reform.

The report supports some of the things the seven-time Cy Young award winner Roger Clemens said in his testimony last month. None of the two sides involved, Clemens or McNamee, was accused of anything, but the report simply implies that the situation is very complicated, and if some of the evidence point to Clemens as lying under oath, other information says he was telling the truth.

“Did Roger Clemens lie to us?” is the question Rep. Tom David asked himself, adding that this is “a far more complicated picture than some may want to believe. […] At this point, the Justice Department is best equipped to investigate that central question and reach a fair conclusion.”

On the other hand, McNamee’s lawyer Richard Emery said about the Republicans’ report that is “nothing more than nit-picking and navel gazing,” The New York Times reports. The report implies that Clemens was not at Jose Canseco’s party in 1998, where McNamee testified his belief that Clemens obtained steroids there.

The Republicans’ report seems to take Clemens’ side, as it also highlighted inconsistencies between the testimony of Andy Pettitte and that of Clemens’ formal personal trainer Brian McNamee.

Since the scandal broke out, Roger Clemens never stopped denying all allegations against him: “I want to state clearly and without qualifications: I did not take steroids, human growth hormone or any other banned substances at any time in my baseball career or, in fact, my entire life,” he said last year.

Both Clemens and McNamee have a lot to lose if they chose to lie under oath, and as it is impossible for both of them to be right; one head will fall, that is certain.
