The lawsuit, filed in a Nevada state court on Monday, alleges the registrar violated state law and asked that the ballots from that polling place be kept separate from other votes, pending any future legal challenges to the results in the state.

A Nevada judge, however, rejected Trump's request.

Judge Gloria Sturman at the Clark County Court said that the order would potentially make public the identities of poll workers, which could put them at risk of harassment.

Most voters are casting their ballots across the United States on Tuesday in the general election but Nevada and several other states allow early voting.
