Vice President Kamala Harris moved swiftly to assert herself as the de facto Democratic nominee for president on Monday, her first full day as a candidate, as virtually every potential remaining rival bowed out and she clinched the support of enough delegates to win the nomination.
The Associated Press said late Monday that Ms. Harris had secured the backing of more than the 1,976 delegates needed to capture the nomination in the first round of voting. The pledged support is not binding until the delegates cast their votes, which party officials said would take place between Aug. 1 and Aug. 7.
