Robert Trump, the younger brother of President Donald Trump, died Saturday night at NewYork-Presbyterian Hospital in Manhattan. He was 71.

The White House did not provide a cause of death. "He was not just my brother, he was my best friend,” the president said in a statement late Saturday. "He will be greatly missed, but we will meet again.”

Robert Trump, who took blood thinners, had experienced brain bleeds that began after a recent fall, according to a close friend of the family’s.
