A Nevada judge rejected a request by Donald Trump's presidential campaign for an immediate order to be issued in its lawsuit over concerns about voting at a polling place in Las Vegas that remained open late last week.

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.

The Trump camp sued the registrar of voters in Clark County over the polling place in Las Vegas that had been allowed to remain open late last week to accommodate people who were lined up to vote.
