Director David Lynch tweeted Tuesday that he supports Dr. Oz, who is defending himself against a group of doctors who want to see him ousted from Columbia University.

Dr. Mehmet Oz, a physician and TV personality, has been embroiled in conflict since a group of doctors asked Columbia University to fire him earlier this month, saying he has an “egregious lack of integrity” and accusing him of promoting “quack treatments and cures in the interest of personal financial gain.” He was also scolded by senators last year for promoting bogus diet products on his show.

Dr. Oz wrote an op-ed for TIME.com defending himself against the allegations. “My exploration of alternative medicine has never been intended to take the place of conventional medicine, but rather as additive,” he wrote. “Critics often imply that any exploration of alternative methods means abandoning conventional approaches. It does not.”

Lynch is himself an advocate of alternative medicine, and his organization, the David Lynch Foundation for Consciousness-Based Education and World Peace, encourages transcendental meditation as treatment for stress-related disorders.
