A federal judge says he almost certainly won't block Wisconsin's voter photo ID law amid allegations that state Division of Motor Vehicles employees are giving out inaccurate information about alternative voting credentials but the state must do more to let people know about the alternative process.

Liberal advocacy group One Wisconsin Institute asked U.S. District Judge James Peterson to block the law after media reports showed DMV workers gave out wrong information on the credentials.

Peterson said Wednesday after a hearing on the request that he's more than reluctant to block the law, saying he's not sure he has the authority since a federal appellate court has upheld the law. But he said wants the state to come up with a better public outreach program so credential applicants know exactly how the process works.

He ordered state attorneys and OWI lawyers to reconvene Thursday morning and hammer out a plan.
