A memorial service was held at the White House on Friday for Robert S. Trump, the late brother of President Donald Trump.

Robert Trump, 71, died last week after being hospitalized in New York. The White House has not given a cause of death.

The president and first lady Melania Trump, as well as younger sister, Elizabeth Trump Grau, were seen walking down the North Portico steps after Robert Trump’s casket. They watched as he was loaded into a hearse and driven away.

Guests at the funeral services include not only members of the Trump family, but also Vice President Mike Pence and Trump's attorney Rudy Giuliani.

“Robert, I Love You. Rest In Peace!” the president had tweeted Friday. The funeral service, which was limited to about 150 guests, will be privately paid for by the president. The service marked the first time in nearly a century that a president held a funeral at the White House for a family member.

The president has previously called Robert Trump his “best friend.” President Trump delivered a 10-minute eulogy.

Robert Trump, a real estate developer and businessman, had been involved in the Trump Organization. He was known for keeping a much lower profile than Donald Trump.

“When he worked in the Trump Organization, he was known as the nice Trump," Gwenda Blair, a Trump family biographer, told The Associated Press. “Robert was the one people would try to get to intervene if there was a problem.”

Robert Trump lived a relatively quiet life as a retiree in New York’s Hudson Valley. In March, he got married for a second time to his longtime secretary, Ann Marie Pallan.
