A painting by George Zimmerman of the Florida attorney who prosecuted him in the shooting death of Trayvon Martin is a copy of an Associated Press photo, a spokesman for the news agency said Friday. According to NBC News, the AP sent a cease-and-desist order to an attorney who has represented Zimmerman, after his brother, Robert, posted the picture to Twitter saying he would entertain offers for its purchase. The AP claims it is an artistic depiction of a copyrighted photo by the news agency. "George Zimmerman clearly directly copied an AP photo to create his painting of Florida State Attorney Angela Corey," Paul Colford, a spokesman for the AP, said in a statement. Neither of the Zimmerman brothers was immediately available for comment. The news agency also said it sent a cease-and-desist letter to Zimmerman's former lawyer, Jayne Weintraub.
