The 65-year-old Administrator for the Centers for Medicare & Medicaid Services (CMS) appeared on Donald Trump Jr.‘s podcast Triggered on Tuesday (April 14).

“He’ll first start off with candy bars — that little candy jar, he’ll call it. He’ll hit the red button. And then comes the diet soda pop, which your dad argues that diet soda is good for him because it kills grass if poured on grass, so therefore it must kill cancer cells in the body,” Dr. Oz explained as Trump Jr. laughed along.

“I’m not even going to argue this right now. You know, we were on Air Force One the other day, and I walk in there because he wants to talk about something, and he’s got … an orange Fanta on his desk. So I say, ‘Are you kidding me?’ And he starts to sheepishly grin. He goes, ‘You know, this stuff is good for me. It kills cancer cells. And then he tells me, ‘It’s fresh-squeezed. So how bad could it be for you?’”

Trump Jr. suggested “maybe he is on to something” due to Trump’s “level of energy, recall, stamina.”

“He doesn’t drink, he doesn’t do drugs, he never did, never tried it,” Trump Jr. said, adding: “So, he always jokes, when he pushes that button for the Diet Coke and the candy, the big bowl of candy, he’s like, that’s my alcohol.”
