About 100 people from the Wichita-based voter advocacy group KanVote rallied at the State House Tuesday urging legislators to repeal the new voter law. But their effort immediately stalled.
The NAACP, the American Civil Liberties Union and Equality Kansas have also called publicly for the law's repeal.
More than 15,900 legal Kansas residents' voter registrations are "on hold" because they have yet to provide proper documents; until then, they can't legally vote.
Secretary of State Kris Kobach says Kansas is actually being lenient by allowing people to fill out registration forms and present proof of their U.S. citizenship later.
House Elections Committee Chairman Scott Schwab acknowledged the law may need to be revised, but said lawmakers need to more time assess its effects.
The ACLU, NAACP and Equality Kansas have threatened to file a federal lawsuit over the law. Kobach is pursuing his own suit to make sure federal officials don't impede the law's enforcement.
