He stood up for Trayvon Martin's killer at trial and on all the talk shows. He fine-tuned the narrative of Martin as a thug. He concealed his own criminal history and conducted white supremacist podcasts. But Frank Taaffe has had a change of heart, and now says Zimmerman is a racist murderer.

Frank Taaffe is George Zimmerman's best friend, who feverishly worked the networks during Zimmerman's murder trial to paint his victim, Trayvon Martin, as a black thug. Frank Taaffe is a white supremacist. And CNN's sister network still loves loves loves bringing Frank Taaffe on to talk about dead black boys.

If you've watched any of CNN or Fox News' coverage of the George Zimmerman trial, you've probably encountered Frank Taaffe, Zimmerman's friend and his most visible defender. But you probably haven't seen his virulently racist Twitter account or heard his appearance on a white supremacist's podcast.
