Biden drops out: Kamala Harris blooms, says will earn nomination as challengers emerge

US Vice President Kamala Harris announced her intention to earn and win the Democratic Party nomination for the presidency, with endorsements from key figures like President Biden, Hillary and Bill Clinton, and Alexandria Ocasio-Cortez.
