NEW YORK (AP) — Ten top physicians want Columbia University to remove celebrity doctor Mehmet Oz from his medical faculty position.
They cite what they call the heart surgeon's "egregious lack of integrity" as host of a television program where he promotes weight loss products.
The letter was sent this week to the dean of Columbia's Faculties of Health Sciences and Medicine.
Led by Dr. Henry Miller of California's Stanford University, the physicians say Oz had "misled and endangered" the public by pushing what they call "quack treatments and cures."
The New York Ivy League school responded Thursday, saying Columbia "is committed to academic freedom and to upholding faculty members' freedom of expression."
As vice chair of Columbia's surgery department, Oz still occasionally teaches.
A show representative did not return a call for comment.
