President-elect Joe Biden delivered an emotional farewell to Delaware on Tuesday one day before his swearing-in, choking up while paying tribute to the state and to his late son, Beau Biden.

Biden spoke from Delaware before departing for Washington, D.C., and he became emotional from the top of the remarks as he thanked Delawareans who have been with him "through the good times and the bad" and said it's "deeply personal that our next journey to Washington starts here."

The president-elect went on to say he'll "always be a proud son of the state of Delaware," emotionally adding that "when I die, Delaware will be written on my heart." He concluded the speech by honoring his late son, Beau Biden, who served as attorney general for the state and died in 2015.

"Ladies and gentlemen, I only have one regret: that he's not here," Biden said. "Because we should be introducing him as president."

Biden was set to depart for Washington shortly after concluding his remarks. He'll be flying to the nation's capitol on a private aircraft, CNN's Jeff Zeleny reports, describing this as "yet another remarkable change in protocol." Zeleny adds, "No immediate word on why he wasn't offered — or isn't flying — on a U.S. government plane, which is standard for a president-elect." Brendan Morrow
