Kamala Harris, D-Calif., pass each other as Harris moves to the podium to speak during a campaign event in Wilmington, Del., Aug. 12, 2020. She’s already broken barriers, and now Vice President 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/Carolyn Kaster, File)
