- Clinton earned four pledged delegates while Bernie Sanders gained three
- The party chairman and vice chairwoman also announced their support of Clinton
Clinton won 777 votes to the Vermont senator's 528.
The former secretary of state, who holds a wide delegate lead over Sanders, earned four pledged delegates, while Sanders gained three.
The party chairman and vice chairwoman, previously uncommitted superdelegates, announced their support of Clinton in light of the caucus results, giving her the support of all five Guam superdelegates.
The small contest is on track with the broader Democratic trend: While Sanders remains competitive, Clinton is on course to rack up the delegates necessary to claim the party's nomination.
Clinton now has 2,224 total delegates -- 1,709 pledged and 515 superdelegates. Sanders has 1,447 total delegates, 1,406 of which are pledged and 41 superdelegates.
To clinch the Democratic nomination, a candidate needs 2,383 delegates. Sanders cannot mathematically win the Democratic nomination on the first ballot without a significant number of superdelegates who are unpledged or have endorsed Clinton.
Next, Clinton and Sanders will face off in West Virginia on Tuesday, followed by contests in Kentucky and Oregon on May 17.
