Robert Trump, the younger brother of US President Donald Trump and a business executive who avoided the spotlight, died on Saturday night, a day after the President visited him in a New York hospital.

President Trump announced the death in a statement. “It is with heavy heart I share that my wonderful brother, Robert, peacefully passed away tonight. He was not just my brother, he was my best friend,” he said.

“He will be greatly missed, but we will meet again. His memory will live on in my heart forever. Robert, I love you. Rest in peace,” Donald Trump said.

Robert Trump, who at 71 was younger than the 74-year-old President, was a business executive and real estate developer. Unlike his reality TV star brother, Robert Trump shunned the limelight.

The cause of death was not revealed. Trump told reporters on Friday that his brother was “having a hard time” with an undisclosed illness. A person familiar with the situation said the brother had been on blood thinners.
