A special prosecutor who took over the investigation eventually found that Zimmerman, who is Hispanic, racially profiled Martin, an African-American, and ignored a police dispatcher's instructions to stop following Martin.
Zimmerman was arrested in April on the murder charge. His wife was arrested on a perjury charge related to the donations in June.
Defense attorney Mark O'Mara told Hannity that he could not comment on the donations, given the case against Shellie Zimmerman.
He did say the case against his client would be an appropriate example of a "stand your ground" defense in Florida. Zimmerman said he had not heard of the law before the incident. He also said the media has made a rush to judgment.
