George Zimmerman is now offering those who donate to his legal defense fund a thank you card complete with his personal signature.

"We are, of course, maintaining the confidentiality of donors," the website for his new legal fund states.

The managers of Zimmerman's legal fund said Wednesday that his money had nearly run out. Countering rumors that the donations were being used to pay attorney fees, the fund managers insisted the money was first being used to pay Zimmerman's living expenses and "pay for costs associated with the defense."

Zimmerman is currently unemployed and free on bond awaiting trial for second-degree murder.

He shot and killed unarmed black teenager Trayvon Martin in Sanford, Florida earlier this year. Zimmerman claims the shooting was in self-defense and cited Florida's controversial "Stand your ground" law.

Police initially failed to press charges against Zimmerman and the incident gained national attention as it was questioned whether the shooting was racially motivated.

"The New George Zimmerman Defense Fund will also be operated with the well-documented assertion that George Zimmerman was the victim of a coordinated public relations attack designed to assert that George acted with racial bias, a public relations attack that was perpetrated with the intent to prejudice the media and the citizens of this country with unfounded misinformation about George, and with the purpose of profiting from a tragedy," the managers of his legal fund said.
