State senators aren’t sure they’ll vote on Kansas Secretary of State Kris Kobach’s proposal to require new voters to prove their U.S. citizenship ahead of this year’s presidential election.

Testimony from opponents took up most of the Senate Ethics and Election Committee’s hourlong meeting Thursday. It adjourned without taking a vote.

It was the committee’s last scheduled meeting of the year. Chairwoman Terrie Huntington, a Fairway Republican, said she’s not sure she can schedule another meeting.

Kansas has a proof-of-citizenship rule set to take effect Jan. 1, 2013, for people registering to vote for the first time in the state. Kobach wants to move up the effective date to June 15.

Kobach said if the committee wants to move forward, it will find a way to have another meeting.
