Dr. Oz: I 'Will Not Be Silenced'

As promised, Dr. Oz is firing back at critics via his own show. In a teaser obtained by CNN, Oz declares that he "will not be silenced" by the 10 doctors who accused him of quackery in a letter to Columbia. "I know I've irritated some potential allies in our quest to make America healthy," he says. "No matter our disagreements, freedom of speech is the most fundamental right we have as Americans. And these 10 doctors are trying to silence that right." About two-thirds of the show will be dedicated to his rebuttal. It airs Thursday, which CNN notes marks the start of the May sweeps season. Expect Oz to attack his critics' credibility by going after their ties to the GMO industry. (His own batting average isn't so hot.)
