Mike Bloomberg won his first contest, carrying the American Samoa Democratic caucuses and winning at least four delegates on Super Tuesday, NBC News projected.
Bloomberg won 49.9 percent of the vote, or 175 votes. Rep. Tulsi Gabbard, D-Hawaii, who was born in American Samoa, received 29.3 percent, or 103 votes, and earned one delegate with 99 percent in. One of American Samoa's six delegates has yet to be awarded.
Sen. Bernie Sanders, I-Vt., won 10.5 percent, and former Vice President Joe Biden won 8.8 percent, both falling short of the 15 percent threshold needed to qualify for any delegates.
Bloomberg's campaign was active in American Samoa.
American Samoa, an unincorporated U.S. territory since 1900, covers seven South Pacific islands and is home to about 55,000 people. Because American Samoa is a territory and does not have any representation in Congress, it has no electoral votes in the presidential election.

Hillary Clinton won the American Samoa caucuses in 2016.
Bloomberg spent roughly $500 million on his presidential campaign, skipping early voting states and instead focusing his efforts on Super Tuesday in hope that he could win big and provide moderate voters weary of Biden's staying power with another option.
