Andy Pettitte is 50-50 about usage of HGH by Roger Clemens

The desire of the federal government connected with the case of Roger Clemens was following: they wanted to prove that this person had lied before the Congress about administration of anabolic steroids and HGH. But the government couldn’t achieve this goal. It was expected that Andy Pettitte would say that Roger Clemens had acknowledged that he had taken the prohibited products during a conversation in 1999 or in 2000. But the testimony of Andy Pettitte was shocking for prosecutors. This man claimed 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 administration of steroids in the Major League Baseball that Roger Clemens admitted to administration of HGH. But he provided 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 understood wrongly Roger Clemens about HGH. Pettitte answered that he is actually 50-50 about this factor.
When the prosecutors heard Pettitte’s answer, they didn’t know what to do. They confirmed that Andy Pettitte never said this way, when he was asked certain times.
The U. S. District Court Judge Reggie Walton noted 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 asked the judge to ignore Andy Pettitte’s testimony because he was 50-50. The attorneys concluded that he probably misunderstood the athlete Roger Clemens or he can’t remember 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. This person hopes that the jury will ignore the testimony which doesn’t support the government.
So, the testimony provided by Andy Pettitte and his wife led to problems. Testimonies of Andy’s wife during the first trial led to the declaration of a mistrial by the judge Walton.
Pettitte confirms that he is a friend of Roger Clemens. Clemens must also claim that they are friends after the last testimony of Andy Pettitte.
