Democratic presidential front-runner Hillary Clinton has won her party's caucus in Guam, her 26th victory in the race for the White House.
The former US secretary of state defeated US Senator Bernie Sanders, according to US media reports quoting the Guam Democratic Party.
Only seven delegates were up for grabs in the Pacific Island territory, meaning the caucus results have little impact on the race.
Although Sanders was victorious on Tuesday in the Indiana primary, raising his pledged delegate count to 1409, Clinton had 1699 after Tuesday's vote plus many more of the so-called super delegates, who are party officials free to vote for whomever they chose.
Both are trying to get to the magic number of 2383 delegates needed to secure the nomination going into the party's convention in July.
On the Republican side, Donald Trump became the last remaining candidate and likely nominee after both his opponents quit the race after the Indiana primary.
The next primary will take place on Tuesday in West Virginia, a state with a large coal industry.
Clinton campaigned this week in the state, but found it difficult to convince voters that a comment she made about closing mines in March was a "misstatement".
According to recent voter surveys, Sanders leads Clinton in the state.
Trump recently scored a major endorsement from the West Virginia Coal Association, which is sure to boost his chances of winning the state in the November 8 election.
