The Missouri House again is pushing this year to require photo identification at the polls.
The House gave initial approval Wednesday to a constitutional amendment and bill that would require voters show photo ID before casting a ballot.
The bill specifies a non-expired ID issued by Missouri or the federal government.
Supporters say the requirements are needed to ensure the integrity of elections.
Democrats say the Republican proposal could make it harder for older people, minorities and women to vote, because they might have more difficulty getting necessary documents.
The Missouri Supreme Court overturned photo ID requirements in 2006. Voters would consider the amendment in November 2016 ballot if it passes the Legislature.
The amendment and bill to implement the requirements for a non-expired photo ID face another House vote.
