President Biden on Monday made his first public comment since announcing his withdrawal from the presidential race a day earlier during a call into the headquarters of Vice President Harris, who he endorsed following his announcement.

Speaking to campaign staffers in Wilmington, Delaware, Harris acknowledged that the past day had "been a roller coaster" after Biden announced he was dropping out of the race. Biden addressed his sudden departure from the race just weeks before the Democratic National Convention.

"I know yesterday's news is surprising, and it's hard for you to hear, but it was the right thing to do," he said. "I know it's hard because you have poured your heart and soul into me to help us win this thing, help me get this nomination, help me win the nomination and then go on to win the presidency."

"I'm going to be working like hell, both as a sitting president, getting legislation passed as well as campaigning," he said.

During her opening remarks, Harris acknowledged the severity of Biden's exit but had only kind words for the commander in chief.
