WASHINGTON (NewsNation) — President Donald Trump’s younger brother, Robert Trump, has been hospitalized 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. 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 hospitalized, but officials said that he was seriously ill.

President Trump spoke about his relationship with his younger brother Friday during a White House briefing.

“I have a wonderful brother. We’ve had a great relationship for a long time — from day one,” said Trump. “That’s a long time ago. He’s in the hospital right now and hopefully he’ll be alright. He’s having a hard time.”

Robert Trump has previously worked for his older brother at the Trump Organization.
