George Zimmerman said Wednesday he wants to auction the gun he used to shoot and kill an unarmed Florida teenager in 2012. Zimmerman, who was a neighborhood watch volunteer at the time of the incident, was acquitted in the death of the 17-year-old African-American after saying he acted in self-defense.

Zimmerman listed the weapon on Thursday, writing: “Prospective bidders, I am honored and humbled to announce the sale of an American Firearm Icon. The firearm for sale is the firearm that was used to defend my life and end the brutal attack from Trayvon Martin on 2/26/2012."

The opening price is set at $5,000, and the bidding is scheduled to begin at 11 a.m. EDT Thursday. Zimmerman said he recently received the gun back from the U.S. Department of Justice.

The item description on the auction site says that "a portion of the proceeds will be used to fight BLM [Black Lives Matter] violence against Law Enforcement officers, ensure the demise of Angela Corey's persecution career and Hillary Clinton's anti-firearm rhetoric." Special Prosecutor Corey had charged Zimmerman with second-degree murder.

The 32-year-old also said that many, including the Smithsonian Museum in Washington, D.C., have expressed interest in owning and displaying the firearm.

“This is a piece of American History. It has been featured in several publications and in current University text books. Offers to purchase the Firearm have been received; however, the offers were to use the gun in a fashion I did not feel comfortable with,” he wrote.

An attorney for Martin's family reportedly declined to comment on Zimmerman, but issued a statement to Fox 35 Orlando Wednesday.

“The Trayvon Martin Foundation is committed to its mission of ending senseless gun violence in the United States. This election, season, we are laser focused on furthering that mission. As such, the foundation has no comment on the actions of that person," the statement read.

Several social media users expressed outrage over Zimmerman's move.

"George Zimmerman I hope you burn in hell you piece of s---," actor Ansel Elgort wrote on his Twitter account.
