FILE - Sen. Kamala Harris, D-Calif. is seen on Capitol Hill, Jan. 10, 2017, in Washington. 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.
