Presumptive Democratic presidential nominee Joe Biden and his running mate Sen. Kamala Harris (D-Calif.) on Sunday offered sympathy to President Trump and his family following the death of his younger brother, Robert Trump.

In a tweet directed at the president on early Sunday, Biden wrote that he and his wife, Dr. Jill Biden, were “sad to learn” of the death of Trump’s brother, who died at the age of 71 on Sunday.

“I know the tremendous pain of losing a loved one — and I know how important family is in moments like these. I hope you know that our prayers are with you all,” wrote the former vice president, who has frequently spoken of his late son Beau Biden, who died from complications related to brain cancer in 2015.

Mr. President, Jill and I are sad to learn of your younger brother Robert’s passing. I know the tremendous pain of losing a loved one — and I know how important family is in moments like these. I hope you know that our prayers are with you all.

Harris also joined him in doing the same on Twitter not long after.

“Doug and I join the Biden family in sending our deepest condolences and prayers to the entire Trump family during this difficult time,” she wrote in the tweet, referring to her husband, lawyer Douglas Emhoff. 

“Losing a loved one is never easy but know that we are thinking of you,” she added.

The White House confirmed the death of Trump’s brother to The Hill on late Saturday. His death comes just days after the president visited his brother while he was being hospitalized in New York. Details of his brother’s condition were not released at the time. 

The White House released a statement from the president shortly after reports emerged of his brother’s death on Saturday night. 

“It is with heavy heart I share that my wonderful brother, Robert, peacefully passed away tonight,” the president said in the statement.

“He was not just my brother, he was my best friend. He will be greatly missed, but we will meet again. His memory will live on in my heart forever. Robert, I love you. Rest in peace,” he added.
