In August of 2020, tapes of Maryanne Trump Barry discussing her brother, Donald, were leaked. Mary Trump, Donald’s niece, recorded 15 hours of her talks with Barry in 2018 and 2019 for her book, Too Much and Never Enough: How My Family Created the World’s Most Dangerous Man, published in July.

Throughout the released tapes, Maryanne is only critical of her younger brother, Donald:

…his goddamned Tweet and the lying. Oh my God. I’m talking too freely, but you know. And the change of stories, the lack of preparation, the lying, the holy sh*t.

Maryanne went on to call Trump a “brat,” and discuss how he paid someone to take his entrance exams for college:

In another tape, Marryane stated that Donald “has no principles,” and disparaged his border policy:

Trump’s response was, “Every day it’s something else, who cares. I miss my brother, and I’ll continue to work hard for the American people. Not everyone agrees, but the results are obvious. Our country will soon be stronger than ever before!”

Maryanne was a federal judge until 2019. She was appointed by Reagan to the District Court of New Jersey and by Clinton to the Third Circuit Court of Appeals. She resigned amid a probe into whether she and her siblings engaged in in fraud to limit the tax liability of their inheritance. Because the investigation in her instance only sought to determine whether she’d violated judicial conduct rules, it concluded with her resignation.
