'The worst thing I've ever heard': Holocaust survivor blasts Harris for comparing Trump to Hitler

The Trump campaign released an ad Friday featuring a Holocaust survivor criticizing Vice President Kamala Harris for comparing former President Trump to Adolf Hitler. 

"I know more about Hitler than Kamala will ever know in a thousand lifetimes," 94-year-old Jerry Wartski, a survivor of Auschwitz, says in the roughly minute-and-a-half advertisement. "For her to accuse President Trump of being like Hitler is the worst thing I've ever heard in my 75 years living in the United States."

Wartski said Trump was a "mensch," a Yiddish term of endearment, arguing "he has always stood with the Jewish people and the State of Israel."

Wartski also demanded an apology from Harris. 

"I know President Trump, and he would never say this, and Kamala Harris knows this," Wartski says. "She owes my parents and everybody else who was murdered by Hitler an apology."

Fox News Digital reached out to the Harris campaign for comment but did not immediately receive a response.
