Shocking testimony of Andy Pettitte at court connected with Roger Clemens’ case

The desire of the federal government connected with the case of Roger Clemens was following: they wanted to prove that this sportsman 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 told him that he had taken the prohibited products during a conversation in 1999 or in 2000. But the statement of Andy Pettitte was shocking for prosecutors. He claimed that he couldn’t confirm that Roger Clemens had used steroids and HGH because he was not sure.
Actually, did the testimony of Andy Pettittte shock the prosecutors of Roger Clemens? This man swore for the 2008 Congressional hearings on administration of steroids in the Major League Baseball that Roger Clemens acknowledged that he had taken 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 may say that he is 50-50 that he has understood wrongly Roger Clemens about HGH. Pettitte answered that he is really 50-50 about this aspect.
When the prosecutors heard Pettitte’s answer, they became confused. They claimed that Pettitte never answered this way, when he was asked certain times.
The judge Reggie Walton noticed that he understood that Andy Pettitte’s answer has been conflicted. Actually, his testimony was following: “I don’t know”.
The attorneys for Roger Clemens utilized the moment of the prosecutors’ confusion. They asked the judge to brush aside Andy Pettitte’s testimony 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 noted that the jury still allows taking in consideration the affirmation of Andy Pettitte. ASUSA Dunham has confirmed that under federal rules jury is allowed to choose which testimony to believe. This person 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 led to problems. Testimonies of his wife during the first trial led to the declaration of a mistrial by the judge Walton.
Pettitte claims that he is a friend of Roger Clemens. Clemens must also confirm that they are friends after the last testimony of Andy Pettitte.
