Andy Pettitte can’t remember details of his conversation with Roger Clemens

The desire of the federal government related to the case of Roger Clemens was following: they desired to prove that this person had lied before the Congress about intake of anabolic steroids and HGH. But the government couldn’t do it. It was expected that Andy Pettitte would claim that Roger Clemens had acknowledged that he had used the prohibited medications during a conversation in 1999 or in 2000. But the testimony of Andy Pettitte was shocking for prosecutors. This person said 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 usage of steroids in the Major League Baseball that Roger Clemens admitted to intake 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 can claim that he is 50-50 that he has understood wrongly Roger Clemens about HGH. Andy Pettitte answered that he is actually 50-50 about this factor.
When the prosecutors heard Pettitte’s answer, they became confused. They stated that Andy Pettitte never said 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 used the moment of the prosecutors’ confusion. They asked the judge to ignore Andy Pettitte’s testimony because he was 50-50. The attorneys concluded that he probably misunderstood Roger Clemens or he forgot the details of the conversation.  
The government has noticed 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 affirmation to believe. He hopes that the jury will ignore the testimony that doesn’t support the government.
So, 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 Roger Clemens’ friend. Clemens must also claim that they are friends after Andy  Pettitte’s last testimony.
