George Zimmerman is speaking for the first time since the U.S. Department of Justice announced it would not bring civil rights charges against him in the 2012 killing of Trayvon Martin.

In a video posted on his lawyer, Howard Iken's website, Zimmerman says in an interview with Iken that he feels he did nothing wrong in killing Martin and that he has a clean conscience. He also shared his thoughts on President Barack Obama's actions in the wake of the shooting, calling the president's comments "racially charged."

Zimmerman was a neighborhood watch volunteer in 2012 when he shot and killed 17-year-old Martin. Zimmerman has said Martin attacked him, and the case spurred debate across the country about civil rights, race and Florida's "Stand Your Ground" law.

In 2013, Zimmerman was acquitted of manslaughter, and he has generally stayed out of the public eye since then.

In the video, Zimmerman faults Obama and Department of Justice officials for stoking racial tension against him.

"For him to make incendiary comments as he did and direct the Department of Justice to pursue a baseless prosecution, he by far over-stretched, over-reached, even broke the law in certain aspects," Zimmerman says, referring to Obama's comment, "If I had a son, he would look like Trayvon."

"I believe that he should have taken the higher road given his position, and been an example, been a leader, as the president should be, and say, 'Let's not rush to judgment,' " Zimmerman adds.

He mentions his last name, saying it may have led to him "being portrayed as a racist white man," when Zimmerman's heritage is half Peruvian.

Zimmerman also says in the video that the Department of Justice should have looked into whether his own civil rights were ever violated.

"They (federal investigators) has various, numerous examples of a bounty being placed on my head, credible threats placed against myself and my family, from who they know to be domestic terrorists," Zimmerman says in the video. "And the president and the attorney general and the federal government declined to do anything about it."
