President Donald Trump may have an undiagnosed learning disorder, his niece Mary Trump claims in her soon-to-be-released tell-all memoir.

“Donald Trump may have a long undiagnosed learning disability that for decades has interfered with his ability to process information,” Mary Trump, a clinical psychologist wrote in Too Much and Never Enough: How My Family Created the World’s Most Dangerous Man.

The book, set to be released July 14 by Simon & Schuster, has been the subject of a highly contested legal battle, with the Trump family arguing its contents violates a 20-year-old nondisclosure agreement signed by Mary Trump.

She also alleges that the president cheated his way into the University of Pennsylvania when he wanted to transfer from Fordham University in Bronx, New York.

Mary writes that Donald worried his grade point average was too low to get in, so he asked “Joe Shapiro, a smart kid with a reputation for being a good test-taker, to take his SATs for him.”

She claims there were no ID restrictions at the time, and Shapiro was compensated for his help.

Shapiro’s widow, Pam Shriver, pushed back against the claim saying her late husband, an attorney and former executive of the Walt Disney Company, “always did the right thing.”

Shapiro died in 1999 after a battle with non-Hodgkin’s lymphoma.

Shriver added that Shapiro attended University of Pennsylvania on the same campus, but she did not believe the two met until after Trump transferred for his junior year.

“When you put somebody’s name in print in a book, you want to make sure the facts around it are correct, especially if they are not living because it’s not like Joe is here and he would have known how to deal with this,” Shriver said.
