ORLANDO, Fla. -- George Zimmerman, the man who fatally shot unarmed 17-year-old Trayvon Martin in Florida in 2012, is selling the gun he used.
The neighborhood watch volunteer was cleared in the death in 2013 after saying he acted in self-defense.
Zimmerman said he is selling the gun partly to raise funds to fight "Hillary Clinton's anti-firearm rhetoric."
The Martin family did not comment.
When asked what he would say to people opposed to the sale, Zimmerman said, "They're not going to be bidding on it so I couldn't care less about them."
The 24-hour online auction begins at 9 a.m. MDT Thursday. The opening price for the 9-millimeter pistol is set at $5,000.
On the auction site gunbroker.com, Zimmerman refers to the gun as an "American icon" and said it was recently returned to him by the U.S. Department of Justice.
"The firearm for sale is the firearm that was used to defend my life and end the brutal attack from Trayvon Martin," Zimmerman wrote on the auction site.
On Feb. 26, 2012, Martin was returning to a relative's house in Sanford, Fla., after buying snacks at a convenience store when he was shot by Zimmerman. Zimmerman was found not guilty of second-degree murder and manslaughter by a jury on July 13, 2013.
Zimmerman claims he received several offers for the gun.
"This is a piece of American History," Zimmerman wrote on the auction site. "It has been featured in several publications and in current University text books."
