Dr. Drew Pinsky’s six-year-old HLN show, called “Dr. Drew On Call” has been canceled by CNN, effective Sept. 22.

In a statement, CNN executive vice president Ken Jautz said he and Pinsky “have mutually agreed to air the final episode of his show on September 22″ but gave no specific reason for the cancellation.

CNN Money, in its reporting of the announcement, connected it to a broader shakeup at HLN, including the end of Nancy Grace’s flamboyant show devoted to criminal court cases.

But the decision came eight days after Pinsky’s comments on a radio show on Aug. 17 questioning the health and medical care of former secretary of state Hillary Clinton, the Democratic nominee for president. After looking at bits and pieces of Clinton’s health-care records she made public in 2015, he said he was “gravely concerned not just about her health, but her health care.”

His comments came as the campaign of Republican presidential nominee Donald Trump, along with its surrogates and supporters, including former New York mayor Rudy Giuliani and Fox News host Sean Hannity, have attempted to portray Clinton as lacking “the mental and physical stamina” demanded by the job, as Trump has put it.

Pinsky’s views, which he said were shared by another physician with whom he had consulted, aired on KABC’s “McIntyre in the Morning.”
