Federal prosecutors couldn’t reach their goal related to Roger Clemens’ case

The desire of the federal government linked with the case of Roger Clemens was following: they desired to prove that this sportsperson had lied before the Congress about administration of anabolic steroids and HGH. But the government couldn’t do it. It was expected that Andy Pettitte would tell the jury that Roger Clemens had admitted that he had applied the forbidden drugs during a conversation in 1999 or in 2000. But the affirmation of Andy Pettitee was shocking for prosecutors. This person stated that he couldn’t affirm that Roger Clemens had used steroids and HGH because he was not sure.
Actually, did the statement of Andy Pettitte shock the prosecutors? This man swore for the 2008 Congressional hearings on administration of steroids in the Major League Baseball that Roger Clemens admitted to usage of HGH. But he pronounced opposite statements at the Barrett Prettyman Federal Courthouse in Washington.
Michael Attanasio, a defense attorney for Roger Clemens, asked Andy Pettitte whether he can affirm that he is 50-50 that he has understood wrongly Roger Clemens about HGH. Pettitte answered that he is indeed 50-50 about this aspect.
When Clemens’ prosecutors heard Pettitte’s answer, they became confused. They affirmed that Pettitte never said this way, when he was asked certain times.
The U. S. District Court Judge Reggie Walton noticed that he understood that Andy Pettitte’s answer has been conflicted. Actually, his statement was following: “I don’t know”.
The attorneys for Roger Clemens utilized the moment of the federal prosecutors’ embarrassment. They requested the judge to ignore the testimony of Andy Pettitte because he was 50-50. The attorneys concluded that he probably misunderstood the athlete Roger Clemens or he forgot the details of the conversation.  
The government has noted that the jury still allows taking into account the testimony of Andy Pettitte. ASUSA Dunham has claimed that under federal rules jury is allowed to choose which testimony to believe. He hopes that the jury will brush aside the testimony which doesn’t support the government.
Thus, the testimony presented by Andy Pettitte and his wife led to problems. Testimonies of his wife during the first trial resulted in the declaration of a mistrial by the judge Walton.
Pettitte affirms that he is a friend of Roger Clemens. Clemens must also confirm that they are friends after Andy  Pettitte’s last testimony.
