John Oliver had harsh words for Dr. Oz on HBO’s “Last Week Tonight.”

He called him out on the latest episode, which aired on Easter, April 17.

Out of his usual 30 minute episode, he spent 16 minutes dedicated to Oz.

Oz has been running for a Senate seat in PA despite living in North Jersey.

John Oliver also reminded audiences of his infamous 2014 debate.

Dr. Oz had been summoned to Capitol Hill, where he was accused to peddling pseudoscience.

Senator Claire McCaskill of Missouri called Oz a “snake oil salesman.”

She asked why he peddled “miracle cures” when he didn’t believe in it.

Oz said he “personally” believes in it but admitted “they don't have the scientific muster to present as fact.”
