The American Civil Liberties Union is pressing registrars across Virginia for voter identification information used on Election Day.
State ACLU executive director Kent Willis says the organization has gotten complaints from dozens of people after last week's General Assembly elections who said they were asked to present a driver's license or other identification to vote.
The ACLU says that at least one registered voter was turned away on November 6 because he was not carrying an ID.
Virginia law allows voters who are not carrying an ID to sign an "affirmation of identity" form.
The civil liberties group said it has sent a Freedom of Information Act request to 134 registrars to seek copies of signs used at polling places and training materials that cover voter identification requirements.
