Fred Trump discussed his new memoir on Good Morning America, calling his uncle, former President Donald Trump, “atomic crazy.”

Fred Trump’s All in the Family: The Trumps and How We Got This Way was published Tuesday by Gallery. A critic for Kirkus called the memoir “more thoughtful than most of the Trump genre but definitely not intended for the fan base.”

On GMA, ABC News reporter Aaron Katersky asked Trump what “the Trump way” is.

“Complex and sometimes cruel,” Trump said. “Every family has their crazy uncle. My uncle Donald is atomic crazy, and he has put his mark on the family history.”

Asked by Katersky what he meant by “atomic crazy,” Trump replied, “It means he does things that, even as much as I know him, when he’s out there now, I sort of shudder and say, Is this the same guy I knew? What’s making him change? What got him this way?

Trump, the father of a disabled son, said that he visited the White House in 2020 to advocate for people with disabilities. His uncle, he said, told him, “These people, all the expenses. They should just die.”

Trump also said that when he was about 10 years old, he was visiting his grandparents when he heard his uncle screaming in the driveway of the house. Donald Trump’s convertible Cadillac Eldorado had been vandalized, his nephew said.

“He used the N-word twice, just saying who he thought probably had done this,” Trump said.

Trump said he doesn’t believe that his uncle is a racist, but that he “uses [people] as props, and when he gets what he needs out of them—votes—he’ll cast them aside.”
