SANFORD, Fla. -

A judge has delayed her ruling on a gag order in the case of a former neighborhood watch leader accused of fatally shooting Florida teenager Trayvon Martin.

Judge Debra Nelson made her decision Friday in Sanford. The prosecution wants the order imposed because it believes George Zimmerman's attorney, Mark O'Mara, has been using a website and both social and news media to influence potential jurors.

The 29-year-old Zimmerman is charged with second-degree murder in the February shooting of Martin. Zimmerman has pleaded not guilty claiming self-defense.

O'Mara launched a website, as well as Twitter and Facebook accounts in April, citing a need to diffuse fraudulent internet entities that claimed to come from Zimmerman. O'Mara contends he didn't discuss any specific evidence and has been compliant with all bar rules.
