Donald Trump’s first wife dead at 73

Donald Trump's first wife Ivana Trump has died, the former president said Thursday.

"I am very saddened to inform all of those that loved her, of which there are many, that Ivana Trump has passed away at her home in New York City," the former president said in a post on his social media platform, Truth Social. "She was a wonderful, beautiful, and amazing woman, who led a great and inspirational life. Her pride and joy were her three children, Donald Jr., Ivanka, and Eric. She was so proud of them, as we were all so proud of her. Rest In Peace, Ivana!"

Ivana Trump was 73. Her cause of death is unknown, reports NBC News.

The New York City Fire Department said that it responded to a report of cardiac arrest at Ivana Trump's Manhattan home Thursday and that the person was dead when authorities arrived.

A senior New York City official told NBC News that Ivana Trump was found on the spiral staircase of her apartment by authorities when they arrived.

City officials said there was no indication of foul play. Her body would be taken to the medical examiner’s office to determine the cause of death.

A former model who was born in Czechoslovakia, the former Ivana Zelnickova married then-businessman Donald Trump in 1977 and held key positions in his businesses, including the Trump Organization, during their 15-year marriage. The couple had three children — Donald Trump Jr., 44, Ivanka Trump, 40, and Eric Trump, 38.

In a statement, the Trump children remembered their mother as "an incredible woman — a force in business, a world-class athlete, a radiant beauty, and caring mother and friend."

"Ivana Trump was a survivor. She fled from communism and embraced this country. She taught her children about grit and toughness, compassion and determination. She will be dearly missed by her mother, her three children and ten grandchildren," they wrote.

Eric Trump told reporters, "It’s been a very sad day guys, a very sad day."
