PHOTOS: Joe Biden's political career through the years

Election 2024 Harris FILE - President Joe Biden walks with Vice President Kamala Harris after speaking on updated guidance on face mask mandates and COVID-19 response, in the Rose Garden of the White House, May 13, 2021, in Washington. She’s already broken barriers, and now Harris could soon become the first Black woman to head a major party's presidential ticket after President Joe Biden’s ended his reelection bid. The 59-year-old Harris was endorsed by Biden on Sunday, July 21, after he stepped aside amid widespread concerns about the viability of his candidacy. (AP Photo/Evan Vucci) (Evan Vucci/AP)
