President-elect Joe Biden bid farewell to his home state of Delaware in an emotional speech, according to Business Insider.

Biden choked up.

“Excuse the emotion, but when I die, Delaware will be written on my heart,” Biden said, invoking Joyce’s famous quote on Dublin being written on his heart.

“Ladies and gentlemen, I only have one regret, that he isn’t here. Because we should be introducing him as president,” Biden said.

“But we have great opportunities,” Biden said as he composed himself after mentioning Beau. “Delaware has taught us anything is possible in this country.”

From Business Insider:

Biden also honored his late son, Beau.

Beau suffered from brain cancer and died at 46 in 2015.

Biden has said his son’s death was a major motivating factor in his decision to run for president.
