Federal prosecutors hoped that Andy Pettitte’s testimony would help to prove that Roger Clemens lied before Congress

The desire of the federal government linked with the case of Roger Clemens was following: they hoped to prove that this sportsperson had lied before the Congress about usage of anabolic steroids and HGH. But the government couldn’t achieve this goal. It was expected that Andy Pettitte would tell the jury that Roger Clemens had told him that he had taken the forbidden drugs during a conversation in 1999 or in 2000. But the statement of Andy Pettitte was shocking for prosecutors. He claimed that he couldn’t affirm that Roger Clemens had used steroids and HGH because he was not sure.
In fact, did the statement of Andy Pettitte shock the prosecutors? This person swore for the 2008 Congressional hearings on application of steroids in the Major League Baseball that Roger Clemens admitted to intake of 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 actually 50-50 about this aspect.
When the prosecutors heard Pettitte’s answer, they didn’t know what to do. They stated that Pettitte never said this way, when he was asked certain times.
The judge Reggie Walton noticed 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 requested the judge to brush aside the testimony of Andy Pettitte 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 responded that the jury still allows taking in consideration the testimony of Andy Pettitte. ASUSA Dunham has confirmed that under federal rules jury is allowed to choose which affirmation to believe. This person hopes that the jury will brush aside the testimony that doesn’t support the government.
Thus, the testimony provided by Andy Pettitte and his wife caused problems. Testimonies of his 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 confirm that they are friends after Andy  Pettitte’s last testimony.
