A Missouri House committee has endorsed legislation requiring voters to show official photo identification at polling places.
The House Elections Committee on Wednesday adopted a bill and a proposed constitutional amendment to implement the change.
Republicans supported the measures and argued they were necessary to prevent election fraud.
The bill would let people obtain one government-issued ID free of charge. It would also allow voters who can't afford an ID or were born before 1941 to cast provisional ballots.
Missouri voters would need to approve the constitutional amendment in November for the legislation to take effect.
