Trayvon Martin's 18th birthday, George Zimmerman in court Tuesday

      SANFORD, Fla. (AP) - A judge in the case of a former neighborhood watch leader accused of shooting Florida teenager Trayvon Martin has denied a defense request to delay the trial.

      George 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.

      Tuesday also marks what would have been Trayvon Martin's 18th birthday.
