Del Quentin Wilber reports on the Crime Scene blog:

The judge overseeing the perjury trial of famed former pitcher Roger Clemens declared a mistrial Thursday after prosecutors played a portion of a video that the jude deemed prejudicial.

U.S. District Judge Reggie B. Walton said prosecutors erred in playing video of Congressional testimony referencing statements made by the wife of a “critical” witness in the case.

“I am very troubled by this,” said U.S. District Judge Reggie B. Walton said before declaring a mistrial.

The declaration came on just the second day of testimony and after it took a week to pick a jury.

The request for a mistrial came from Clemens’ lawyers after prosecutors mistakenly played a portion of Congressional testimony that referenced the wife of former pitcher Andy Pettitte, a friend and former teammate of Clemens.
