Obama mocked Oz for his past health recommendations, accusing him of sellingsnake oil.

John Fetterman is the Democratic candidate for Pennsylvania lieutenant governor. The former president said that Oz was a celebrity doctor and TV show host who had pushed several medical claims that were not backed by science.

Are you interested in losing weight? Take it with you wherever you go. Did you have leg pain? It's possible to try lavender soap. Do you want to prevent Alzheimer's? It's palm oil. Obama appeared to hold back laughter as he described a miracle solution. None of these things have been proven to work and some may be harmful. You have to believe and give your credit card info.

It was easy to joke about Oz's "quack remedies" but they said something about the doctor.

Obama said that if someone is willing to sell snake oil to make a buck, he's probably willing to sell it to get elected.

Insider previously reported that all of the products Obama mentioned were pushed on Oz's show. According to Oz, putting a bar of lavender soap under your sheets could help you sleep, as well as other claims.

Oz's show raked in millions of dollars from companies whose products he promoted.

A doctor who worked on Mehmet Oz's show told the AP that they did a lot of bull.

Oz's campaign said the show was very careful about revealing its paid partnerships. Oz said that he was proud to help so many people.

Fetterman's speech was affected by the stroke he had in May, and Obama was campaigning for him. The race could decide control of the Senate.

A representative for Oz didn't reply immediately.
