Zimmerman's attorneys presented a motion Tuesday asking Judge Debra Nelson to push the trial from mid-June back to November. They say the prosecutor has been slow in turning over needed evidence. The state attorney denied the accusation. 

Judge Debra Nelson noted Zimmerman's lead attorney had been in the case nearly a year and says the problems he's having getting evidence are not insurmountable.

Zimmerman is claiming he acted in self-defense in shooting Martin last year and has pleaded not guilty to second-degree murder.
