Donald Trump’s eldest sister Maryanne Trump Barry has died at the age of 86.
Ms Trump Barry, a former federal judge, died at her home in Manhattan and was found early on Monday morning, according to reports.
The New York City Police Department said an 86-year-old woman was found unconscious and unresponsive inside the bedroom of a Fifth Avenue apartment and was later confirmed dead.
An investigation is ongoing, police said.
Mr Trump, 77 – who is facing a civil fraud trial in New York – is yet to comment on his sister’s death.
Ms Trump Barry, who was born in Queens, New York, in 1937, was the eldest child of Fred Trump and Mary Anne MacLeod Trump.
While working in the US Attorney’s Office, she was appointed to the US District Court for New Jersey by President Ronald Reagan in 1983.

She was later appointed to the US Court of Appeals for the Third Circuit in Philadelphia in 1999 by President Bill Clinton.
Ms Barry served in that role until 2017 until her younger brother was inaugurated as US president, according to the Associated Press.
Her retirement as an appellate judge in 2019 ended a civil misconduct inquiry following allegations in a New York Times article that she and her siblings, including then-President Trump, evaded inheritance taxes.
