President Donald Trump plans to travel to New York to visit his seriously ill brother, Robert Trump, a senior administration official confirmed Friday.

Trump will travel to Manhattan on Marine One chopper. Robert Trump (left) embraced his brother after the president-elect delivered his acceptance speech in November, 2016.

A White House official said Trump "has a very good relationship with his brother and his brother is very special to him."

Robert Trump was recently hospitalized in the intensive care unit at Mount Sinai Hospital in New York City earlier this summer. He spent a week in the ICU.

Officials didn't disclose when Robert was re-admitted to the hospital. Robert Trump, left, is pictured with (L-R) ex-wife Blaine Trump, Donald Trump and his ex-wife, Ivana Trump, in a photo dated 2005.

Robert Trump filed a lawsuit last month seeking to block the release of his niece Mary Trump's tell-all book, titled Too Much and Never Enough.

At the time, he said he was "deeply disappointed" in his niece's efforts to profit off his brother's good name.

He said the "entire family" were "so proud of my wonderful brother, the president."
