Mary Trump has lobbed one grenade on her uncle already — and the presidential niece is just getting started.

The daughter of President Donald Trump’s brother reportedly revealed she leaked tax documents that formed the basis of a Pulitzer Prize-winning story about the president’s finances.

And the news gets worse for the man in the White House.

Mary Trump reportedly plans to spill more of the family secrets in a tell-all memoir due to hit shelves in August, just as the presidential campaign heats up, according to the Daily Beast.

Among the stories she will relate are negative remarks by President Trump’s sister, retired federal judge Maryanne Barry Trump, about her brother.

Mary Trump, 55, is the daughter of Fred Trump Jr. and the oldest grandchild of Fred Trump Sr., the New York real estate mogul who gave President Trump his start. Fred Trump Jr. died at age 42 of a heart attack exacerbated by alcoholism

The book, “Too Much And Never Enough,” will be published by Simon & Schuster on Aug. 11.

It’s not the first time bad blood has boiled over between Mary Trump and her mercurial uncle.

Mary Trump, a PhD psychologist, and her brother challenged their grandfather’s will by claiming he was improperly pressured by Donald Trump and his two other siblings to shaft them.

The tax documents that she reportedly leaked revealed that President Trump benefited from a series of allegedly fraudulent transactions and got up to $400 million in cash injections into his flailing real estate empire in the 1990s.

Trump often lashes out at perceived critics on Twitter. But he has not recently mentioned Mary Trump or her criticism of him in public.
