Trump’s niece really doesn’t like him.

“I think he’s freaking out,” said Michael D’Antonio, author of Never Enough: Donald Trump and the Pursuit of Success. “He will treat her savagely.”

On Sunday, Axios reported that Trump insists Mary Trump is “not allowed” to write her book, because doing so would violate a non-disclosure agreement she signed.

Trump told Axios: “She’s not allowed to write a book. When we settled with her and her brother, who I do have a good relationship with – she’s got a brother, Fred, who I do have a good relationship with, but when we settled, she has a total … signed a nondisclosure.”

It’s interesting how he extorts NDAs from people. I guess he must have something to hide?

Mary, 55, is the daughter of Fred Trump Jr, the president’s older brother, who died in 1981 at the age of 42 from a heart attack linked to alcoholism. She has bachelor’s and master’s degrees in English literature, as well as a PhD in clinical psychology from Adelphi University in New York, according to Forbes.

Meaning she’s a whole lot smarter than Trump. Trump at this point would flunk second grade.

D’Antonio commented: “It makes her someone that Donald would fear on a very elemental level. She thinks for herself, she’s analytical when it comes to humans and she can express herself, so this is a nightmare for him.”

We can hope so.

The president is now reportedly considering suing Mary over the memoir, due to be published on 28 July by Simon & Schuster. It is expected to disclose Mary was a key source of confidential documents for a Pulitzer prize-winning New York Times investigation into Trump’s personal finances.

Squirm, Donnie. Squirm and sweat and lose sleep.
