Real estate developer Robert Trump, the younger brother of the US president, has been admitted to a hospital in New York after "falling very ill", according to ABC News, citing sources.
ABC News reported that White House Press Secretary Kayleigh McEnany confirmed the hospitalisation, adding that the president and his brother "have a very good relationship" and that Donald Trump would be providing more details on the matter sometime later.
In June, Robert Trump spent more than a week in the intensive care unit at Mount Sinai Hospital in New York, reports say.
The book tells the story of the Trump family in detail and describes how Donald Trump became the man he is today, while making it clear that its author does not want her uncle to be re-elected.
