Barry died at her home in New York City, The New York Times first reported on Monday.
Her death followed a call about a person in cardiac arrest around 4 a.m. Monday, ABC News reported, citing sources. There were no signs of trauma or foul play.
Barry served as a senior judge on the U.S. Court of Appeals for the 3rd Circuit until her abrupt retirement in 2019.
Her decision to step down halted a civil misconduct inquiry into whether she participated in fraudulent tax schemes with her family — including the former president — in the 1990s, which would have violated judicial conduct rules. The investigation was closed since retired judges are not subject to conduct rules.
The inquiry followed the Times reporting that the Trump siblings hid millions of dollars of transfers from their father, Fred Trump, to avoid paying gift and inheritance taxes. This money was transferred through a sham company that was owned by Fred Trump’s children.
Barry said little publicly about her brother’s presidency, though in 2020 their niece, Mary L. Trump, released an audio recording of her aunt disparaging Donald Trump and calling him a liar.
“He has no principles. None. None. And his base, I mean my God, if you were a religious person, you want to help people. Not do this,” Barry said while reacting to the now-former president’s U.S.-Mexico border policies that took children from their parents.
“I’m talking too freely, but you know. The change of stories. The lack of preparation. The lying. Holy shit,” she said.
Fred Trump Jr., who was Fred Trump’s eldest son and the father of Mary Trump, died of a heart attack at 42 in 1981.
The former president, 77, and his other sister, 81-year-old Elizabeth Trump Grau, are now the last living Trump siblings.
Donald Trump did not immediately issue a statement on his sister’s death.
