Memoir On July 30, 2024, during Donald Trump's campaign in the 2024 United States presidential election, Trump published a memoir titled All in the Family: The Trumps and How We Got This Way. The memoir details his experiences with his uncle Donald Trump and his grandfather Fred Trump.

Allegations against Donald Trump In the memoir and interviews regarding it, Trump claimed that Donald Trump, in response to his request to refill his disabled son William's medical fund, told him to let William die instead, claiming that William does not recognize him and that he should move to Florida afterward. According to Trump, Donald Trump has never met William. Trump explicitly stated that, while he does not believe that his uncle is a racist, he does believe that he uses people as if they were props and will "cast them aside" when he gets what he desires out of them.

Donald Trump personally responded to Trump's allegations in a statement to The Washington Post, claiming that he has helped Trump more than anyone else in his life, only to get allegations in return. He added that he believes Trump's sister, Mary L. Trump, convinced him to make the allegations. However, Trump claimed that he has not spoken to Mary since she published her 2020 book that similarly criticized Donald Trump, Too Much and Never Enough, nor has he read her book. However, he stated that he was willing to attend Donald Trump's inauguration if his uncle won the election and if he was invited.

In March 2025, Trump critiqued the upcoming budget plan that would eventually lead to the 2025 United States federal government shutdown, claiming that the cuts to Medicaid would be devastating for his disabled son, William, as well as for "tens of millions of people like William", and accused the cuts of lacking "humanity and decency". In June 2025, Trump raised concerns about Donald Trump's mental health, claiming that Donald Trump's behavior at the time paralleled the behavior of his family members such as Fred Trump Sr. before their diagnoses of Alzheimer's disease. He added that his uncle used to be able to "stick to a message" but had lost the ability to do so.

Personal life Trump lives with his wife, Lisa Beth Trump, in Connecticut, and they have three children together. William is nonverbal and uses a wheelchair. He has been living in a group home about 20 minutes from his parents' home for "the last couple years", according to Trump in 2025. William attended Central Middle School as a child, and reportedly enjoyed ice cream, swimming, peanut butter sandwiches, and reggae at that point in his life.

Trump's uncle, Donald Trump, has given him significant financial assistance to aid with William's care. In September 2024, Trump claimed that a spokesperson for his uncle alerted him a few weeks prior that William's medical fund had been dissolved.
