Donald Trump’s younger brother Robert has been admitted to hospital in New York, according to the White House. The president is expected to visit his 72-year-old brother at a hospital in Manhattan on Friday, according to White House spokesman Judd Deere.
Mr Trump was already scheduled to visit his property in Bedminster, New Jersey, on Friday.
The White House did not immediately release details about why Robert Trump had been taken to hospital, but officials said he was seriously ill.
The president has “a very good relationship with his brother who is very special to him”, Mr Deere said.
Robert Trump recently filed a lawsuit on behalf of the Trump family seeking to stop publication of a tell-all book by the president’s niece Mary, titled Too Much And Never Enough.
The president has said her book was a violation of a non-disclosure agreement she signed in connection to a financial settlement she received from the Trump family.
Mary is a daughter of the brothers’ eldest sibling, Fred Trump Jr, who struggled with alcoholism and died in 1981 at the age of 43.
No family members joined Fred Jr, known as Freddy, at the hospital on the night he died, she said, adding that Donald Trump went to the movies with another sibling instead.
Robert Trump has previously worked for his older brother at the Trump Organisation.
