TOPEKA, Kan. (AP) — Republican Secretary of State Kris Kobach is likely to face questions during a televised debate about a proof-of-citizenship requirement for new Kansas voters enacted at his urging.

Kobach makes his second televised joint appearance with Democratic challenger Jean Schodorf on Wednesday night from the studio of Topeka public television station KTWU.

Kobach is seeking a second four-year term. He successfully pushed the Legislature to enact a 2013 law that requires new voters to provide election officials a birth certificate, passport or other proof of U.S. citizenship.

Schodorf voted for the policy as a state senator but says Kobach has poorly administered it.

Kobach contends the requirement prevents voter fraud. But the voter registrations of thousands of Kansas residents are on hold because they haven’t yet complied.
