Colorado Republicans frustrated in their efforts to tighten citizenship checks are hoping to turn to voters.
Most Republican senators signed on to three proposals Monday to ask voters to approve citizenship checks. One bill would allow elections officials to require proof of citizenship. Another would require an elected official to provide proof of citizenship before taking office and a third would stiffen worker-eligibility requirements for employers.
Republicans say they have been frustrated to see their citizenship proposals lose in the Democratic Senate, so they want to ask voters to change the state constitution. However, the measures would have to clear the same committee that rejected other immigration bills earlier this year.
