The final day of testimony featured Zimmerman on the stand for the second consecutive day, often contentiously sparring with U.S. Attorney John Docherty. During the morning session, the prosecutor attempted to browbeat Zimmerman into admitting that he had repeatedly lied to FBI investigators when they initially interviewed him. The pair repeatedly jostled over exactly what constitutes a lie. "A lie," Zimmeraman stated at one point, "would be something like your opening statement to the jury."
U.S. District Court Judge Ann Montgomery was not amused. She instructed the jury to ignore the statement and warned Zimmerman to limit his testimony to answering questions posed by the prosecutor.
