O.J. Simpson has been listening to testimony from his daughter and other witnesses in a Las Vegas courtroom, where he's hoping to get a new trial in the armed robbery-kidnapping case that sent him to prison.

He's now served more than four years of a minimum nine-year prison term.

He'll be in court all this week to claim that he had poor legal representation in the trial, involving the gunpoint robbery of two sports memorabilia dealers in a Las Vegas hotel room.

The former football hero and a new set of lawyers hope to convince a judge during a hearing that began Monday that trial lawyer Yale Galanter had conflicted interests and shouldn't have handled Simpson's armed case.

Simpson appeared in court wearing a blue jail uniform. His hair was short and grayer than it was during a previous court appearance in 2008.
