Donald Trump on Tuesday sued the registrar of voters in Nevada’s Clark County over a polling place in Las Vegas that had been allowed to remain open late last week during an early voting period to accommodate people. Many of the people who voted who were lined up to cast ballots were Hispanics.

However, a Nevada judge rejected a Trump’s request for an immediate order in its lawsuit. 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.
