Reno, Nevada (CNN) The chairman of the Nevada Republican Party argued Saturday during a rally here for Donald Trump that polling locations stayed open late to accommodate long lines of voters "so a certain group could vote." The chairman, Michael McDonald, was referring to a polling location in Clark County, which is 30% Hispanic and the county in which Las Vegas is located. The polling location stayed open to allow voters who were already in line -- many of whom waited more than two hours, according to local reports -- to cast their ballots. "Last night, in Clark County, they kept a poll open 'til 10 o'clock at night so a certain group could vote," McDonald said in introductory remarks at the rally. "The polls are supposed to close at 7. This was kept open until 10. Yeah, you feel free right now? You think this is a free and easy election? That's why it's important."Trump then suggested that the polling location's extended closing time is a sign of a "rigged system"Polling locations are non-partisan
More than 57,000 people voted in _ on Friday, the largest single-day early voting turnout in the county, according to data from the Nevada secretary of state's office that's based on the party registration of those who have voted.
