Robert Trump, the younger brother of President Donald Trump, is hospitalized in New York, the White House confirmed Friday.
Trump is expected to visit his brother Friday in New York, a source familiar with the matter told CNN.
'Can confirm the report that the President's brother is hospitalized,' deputy press secretary Judd Deere told CNN.
During a White House briefing on Friday, Trump declined to provide reporters with details on his brother's illness.
'I have a wonderful brother. We have a great relationship for a long time, from day one, so long time ago. And he's in the hospital right now,' Trump said when asked what ailed his brother.
'Hopefully he'll be alright, but he's -- he's pretty -- he's having a hard time,' he added.
Robert Trump was previously hospitalized in the spring with a serious condition.
A senior administration official said Friday that the President 'has a very good relationship with his brother and his brother is very special to him.'
The news was first reported by ABC News.
Robert Trump was a former top executive at the Trump Organization. He's one of four other siblings to the President, including the late Fred Trump, Jr.
In June, Robert Trump filed a temporary restraining order in an attempt to block the publication of an unflattering tell-all book by Mary Trump, the daughter of Fred Trump.
