Former Atlanta Fire Chief Kelvin Cochran is suing the city for wrongful termination, and now he has the backing of a powerful ally in the federal government.

Cochran, you may recall, was dismissed by Mayor Kasim Reed earlier this year. He claims he was fired for the religious beliefs he expressed in a book he wrote in 2013. Reed argued Cochran broke city protocol and shouldn't have spoken out during a month-long suspension, and that the fire chief didn't lose his job because the 162-page book included two brief passages describing traditional Christian teachings about homosexuality.
