His son Eric Trump said it was “a very sad day, a very sad day” as he left home on Thursday.
Czech-born ski racer and businesswoman Ivana Trump was born Ivana Zelnickova in 1949.
She was married to the former president from 1977 to 1992 and they had three children together: Donald Jr., Ivanka and Eric.
The Trumps became a power couple of the 1980s, and she managed one of his casinos in Atlantic City and helped decorate Trump Tower. Their marriage ended in a messy public divorce after Donald Trump met his next wife, Marla Maples.
But in recent years, Ivana Trump has been on good terms with her ex-husband. She wrote in a 2017 book they talked about once a week.
His death came during a difficult time for the Trump family. Two of his children, Donald Jr. and Ivanka, as well as the former president were due to appear in the coming days for questioning as part of the New York Attorney General’s civil investigation into the family’s business practices. But the attorney general’s office agreed to postpone depositions – a term for extrajudicial examination under oath – because of Ivana Trump’s death.
