Andy Pettitte’s testimony shocked federal prosecutors at court linked with Roger Clemens’ case

The desire of the federal government related to the case of Roger Clemens was following: they hoped to prove that this sportsperson had lied before the Congress about application of anabolic steroids and HGH. But the government couldn’t achieve this goal. It was expected that Andy Pettitte would claim that Roger Clemens had acknowledged that he had applied the banned preparations during a conversation in 1999 or in 2000. But the testimony of Andy Pettitte was shocking for prosecutors. He stated that he couldn’t affirm 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 person swore for the 2008 Congressional hearings on usage of steroids in the Major League Baseball that Roger Clemens acknowledged that he had taken HGH. But he provided opposite affirmations 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 the answer of Andy Pettitte, they became confused. They affirmed that Andy Pettitte never answered this way, when he was asked certain times.
The judge Reggie Walton claimed 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 ignore Andy Pettitte’s testimony because he was 50-50. According to the attorneys, he probably misunderstood Roger Clemens or he can’t remember the details of the conversation.  
The government has noticed that the jury still allows taking in consideration the testimony of Andy Pettitte. ASUSA Dunham has claimed that under federal rules jury is allowed to choose which testimony to believe. This person hopes that the jury will ignore the testimony which doesn’t support the government.
Thus, the testimony presented 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 affirms that he is a friend of Roger Clemens. Clemens must also confirm that they are friends after Andy  Pettitte’s last testimony.
