On June 4 and 5, Clinton won two victories in the Virgin Islands caucus and Puerto Rico primary. On June 6, 2016, the Associated Press and NBC News reported that Clinton had become the presumptive nominee after reaching the required number of delegates, including pledged delegates and superdelegates, to secure the nomination, becoming the first woman to ever clinch the presidential nomination of a major U.S. political party. On June 7, Clinton secured a majority of pledged delegates after winning primaries in California, New Jersey, New Mexico, and South Dakota, while Sanders won only Montana and North Dakota. Clinton also won the final primary in the District of Columbia on June 14. At the conclusion of the primary process, Clinton had won 2,204 pledged delegates (54% of the total) awarded by the primary elections and caucuses, while Sanders had won 1,847 (46%). Out of the 714 unpledged delegates or "superdelegates" who were set to vote in the convention in July, Clinton received endorsements from 560 (78%), while Sanders received 47 (7%).
