Shocking testimony presented by Andy Pettitte at Barrett Prettyman Federal Courthouse

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 application of anabolic steroids and HGH. But the government was not able to reach this goal. It was expected that Andy Pettitte would claim that Roger Clemens had acknowledged that he had administered the banned products during a conversation in 1999 or in 2000. But the testimony of Andy Pettitte was shocking for prosecutors. He said that he couldn’t affirm 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 usage of steroids in the Major League Baseball that Roger Clemens admitted to usage of HGH. But he pronounced opposite affirmations at the Barrett Prettyman Federal Courthouse in Washington.
Michael Attanasio, a defense attorney for Roger Clemens, asked Andy Pettitte whether he may claim that he is 50-50 that he has understood wrongly Roger Clemens about HGH. Pettitte answered that he is indeed 50-50 about this factor.
When the prosecutors heard Pettitte’s answer, they became confused. They confirmed that Pettitte never answered this way, when he was asked several times.
The U. S. District Court Judge Reggie Walton noted that he understood that Andy Pettitte’s answer has been conflicted. In fact, his statement was following: “I don’t know”.
The attorneys for Roger Clemens utilized the moment of the federal prosecutors’ embarrassment. They asked the judge to brush aside Andy Pettitte’s testimony because he was 50-50. According to the attorneys, he probably misunderstood the athlete Roger Clemens or he forgot the details of the conversation.  
The government has noticed that the jury still allows taking into account the testimony of Andy Pettitte. ASUSA Dunham has confirmed that under federal laws jury is allowed to choose which affirmation to believe. This person hopes that the jury will ignore the testimony that doesn’t support the government.
Thus, 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.
