Republican President Donald Trump's campaign said on Saturday it had sued in Arizona, alleging that the Southwestern state's most populous county incorrectly rejected votes cast on Election Day by some voters in the U.S. presidential race.
The lawsuit, filed in state Superior Court in Maricopa County, said poll workers told some voters to press a button after a machine had detected an "overvote."
The campaign contended that decision disregarded voters' choices in those races, saying new voting machines were used on Election Day on Tuesday. The lawsuit suggested those votes could prove "determinative" in the outcome of the race between Trump and Democrat Joe Biden, who was declared the winner on Saturday by major television networks.
