In the first attempt to try Clemens last July, Walton declared a mistrial on the second day of testimony after the government showed inadmissible evidence to the jury.It was in pretrial motions in advance of the July proceedings that Walton granted a defense motion to exclude mention of an affidavit Andy Pettitte's wife, Laura, had given to the House Committee saying that her husband told her about a conversation he had with Clemens regarding the use of performance-enhancing drugs. Walton ruled that her affidavit could not come into the trial unless the defense attempted to attack Andy Pettitte's credibility, which the defense said in its opening statement before the jury that it did not intend to do. When the prosecution early in its case showed video including a written transcript of Congressman Elijah Cummings (D-Md.) questioning Clemens during the 2008 hearing and discussing Laura Pettitte's affidavit, the trial came to an abrupt halt. Within hours, Walton granted a defense motion for mistrial, sending the case into limbo while Walton weighed arguments about whether the trial could be restarted. Walton, a U.S. District Judge for the District of Columbia, denied a defense motion in September to dismiss the charges against Clemens and bar a retrial, setting the original trial date of April 17, now bumped up a day to a Monday.
