NASHVILLE, Tenn. (AP) -- The bill proposed by Tennessee Sen. Bill Ketron to allow student identification issued by state higher education institutions to be used for voting purposes has hit a snag.
The measure was put off for a week on Thursday to address concerns brought by another Republican lawmaker about the validity of using a college ID.
Ketron said the legislation would clear up any confusion regarding locally issued cards that he said were not supposed to be allowed under the original law passed two years ago. He said that includes library cards issued by local governments.
The city of Memphis and two residents sued the state last year after election officials refused to accept a city-issued library card with a photo as voter identification.
The Tennessee Court of Appeals has upheld the state voter ID law as constitutional but also allowed Memphis residents to use the library card as identification to vote.
