The American Civil Liberties Union of Rhode Island says there were problems at some polling places during the presidential election, though voting went smoothly in most locations.
The ACLU said Friday that some lawful voters were turned away from the polls in November because Rhode Island requires voters to show photo identification.
The civil liberties organization didn't have a specific number of voters, but says poll monitors reported occurrences in Providence and Warwick.
It says some voters without proper identification either weren't provided a provisional ballot or told to vote at city hall.
Secretary of State Nellie Gorbea says she's convening a task force to improve poll worker training and efficiency at the polls.
The ACLU says polling location changes also caused confusion. It wants the voter identification law repealed.
