Dr. Mehmet Oz responded to his critics today on television. Ten doctors have urged Columbia University to fire Dr. Oz. He's vice chair of Columbia's surgery department. His critics say much of the advice on his TV show has been found to be unsupported by scientific evidence, and in some cases, contradicted by it. They also accuse him of - and, these are their words - a lack of integrity by promoting quack treatments and cures in the interest of personal financial gain. Columbia has stood by his freedom of expression and today Dr. Oz did the same.
MEHMET OZ: Freedom of speech is the most fundamental right we have as Americans. And these 10 doctors are trying to silence that right. So I vow to you right here, right now, we will not be silenced. We will not give in.
