Andy Pettitte presented shocking testimony at Barrett Prettyman Federal Courthouse in Washington

The desire of the federal government connected with the case of Roger Clemens was following: they hoped to prove that this athlete had lied before the Congress about administration of anabolic steroids and HGH. But the government couldn’t reach this goal. It was expected that Andy Pettitte would tell the jury that Roger Clemens had admitted that he had used the prohibited preparations during a conversation in 1999 or in 2000. But Pettitte shocked the prosecutors. This man claimed that he couldn’t confirm that Roger Clemens had used steroids and HGH because he was not sure.
In fact, why were the prosecutors shocked by the affirmation of Andy Pettittte? This person swore for the 2008 Congressional hearings on application of steroids in the Major League Baseball that Roger Clemens admitted to usage of HGH. But he presented opposite statements at the Barrett Prettyman Federal Courthouse in Washington.
Michael Attanasio, a defense attorney for Roger Clemens, asked Andy Pettitte whether he may affirm that he is 50-50 that he has misunderstood Roger Clemens about HGH. Pettitte answered that he is indeed 50-50 about this aspect.
When Clemens’ prosecutors heard the answer of Andy Pettitte, they didn’t know what to do. They affirmed that Pettitte never answered 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 prosecutors’ confusion. They requested the judge to brush aside the testimony of Andy Pettitte because he was 50-50. According to the attorneys, he probably misunderstood Roger Clemens or he forgot the details of the conversation.  
The government has responded that the jury still allows taking in consideration the affirmation of Andy Pettitte. ASUSA Dunham has pointed out that under federal rules jury is allowed to choose which affirmation to believe. He hopes that the jury will brush aside the testimony that doesn’t support the government.
So, the testimony presented by Andy Pettitte and his wife caused problems. Testimonies of his wife during the first trial resulted in the declaration of a mistrial by the judge Walton.
Pettitte claims that he is a friend of Roger Clemens. Clemens must also claim that they are friends after Andy  Pettitte’s last testimony.
