CNN has canceled the television show of Dr. Drew Pinsky, a week after the celebrity doctor questioned Hillary Clinton's healthcare.

The network said Thursday that Pinsky's "Dr. Drew On Call" HLN show will air its last episode on Sept. 22. CNN Vice President Ken Jautz didn't give a specific reason for ending the show, but the announcement comes days after Pinsky said on a radio show that Clinton was receiving a "1950s level of care."

Asked about Clinton's medical history, which indicates she has hypothyroidism and a condition known as deep vein thrombosis that causes blood clots, Pinsky criticized the treatment she was receiving, saying he feels it was out of date.

"It just seems like she's getting care from somebody that she met in Arkansas when she was a kid, and you've got to wonder," Pinsky said. "You've got to wonder. It's not so much that her health is a grave concern. It's that the care she's getting could make it a concern."

Some of Clinton's opponents, including Donald Trump's presidential campaign, have been circulating rumors lately about the Democratic presidential nominee's health. But the Clinton campaign has pushed back hard, pointing to a letter last year from Clinton's doctor outlining her chronic conditions, explaining how they're being managed and concluding that she is physically fit to be president.

Pinsky, who also has produced the VH1 shows "Celebrity Rehab with Dr. Drew" and its sex rehab spinoff, had hosted the HLN show for more than five years.

"It has been a privilege working at HLN," Pinsky said in a statement. "My executive producer Burt Dubrow and our outstanding staff and contributors were consistently exceptional. I am very excited to stay within the CNN Worldwide family as a contributor."
