George Zimmerman is selling the gun he used to kill Trayvon Martin , an unarmed black teenager, during a 2012 confrontation in Sanford, Florida.

"I'm a free American ," he told Fox 35 in Orlando. "I can do what I like with my possessions."

Zimmerman wrote in the auction description of the Kel-Tec PF-9 9mm handgun that he plans to use some of the money to "fight BLM violence against Law Enforcement officers, ensure the demise of Angela Correy's [sic] persecution career and Hillary Clinton's anti-firearm rhetoric."

Angela Corey is the Republican state attorney who charged Zimmerman with second-degree murder in the Martin shooting.
