An ex-neighborhood watch volunteer charged with killing Trayvon Martin is again asking for a new judge.

George Zimmerman's attorney, Mark O'Mara, filed a motion Friday asking that Circuit Judge Ken Lester be disqualified from the case.

Zimmerman said Lester's comments in a bond order led him to believe Lester is prejudiced against him. The judge said in the order that Zimmerman and his wife misled him about their finances.

Zimmerman also said he can't get a fair trial with Lester presiding over the case.

Zimmerman is charged with second-degree murder. He has pleaded not guilty, claiming self-defense.

Zimmerman asked for a new judge after he was charged in April, claiming there was a potential conflict of interest with the judge. His request was granted and the case was turned over to Lester.
