The New York City medical examiner ruled that the death of Ivana Trump was accidental.
The former president announced the death of his wife on social media. She was older than 70.
The New York City Office of Chief Medical Examiner said that Ivana Trump died from injuries to her torso.
The office will not comment on the investigation after releasing this determination.
Donald Trump's first wife, Ivana, was the mother of three of his children.
Ivana fled to the US from Canada after the Czech Communist Party took over. She and Donald Trump were married for over a decade before their public divorce in 1992, which was finalized shortly before he proposed to his second wife.
Donald Trump wrote on Truth Social that he was "very sad to inform all of those that loved her, of which there were many." She was an amazing woman who led a great and inspiring life.
