MADISON, Wis. -

 Attorneys for the state of Wisconsin have filed a report acknowledging some Department of Transportation employees supplied inaccurate information to people looking to obtain alternative credentials for voting in lieu of photo identification.

But the filing Friday says the agency has since corrected the issues and upgraded training.

U.S. District Judge James Peterson ordered the state to investigate media reports that Division of Motor Vehicle employees supplied inaccurate information to people looking to obtain voting credentials because they lacked supporting documents to get an ID.

The report acknowledged some DMV employees communicated inaccurate or incomplete information. But it says the Transportation Department sent undercover state troopers into 31 offices and they were given the correct information. The DMV also has mandated new training, created credentialing specialists and set up a hotline.

Peterson will consider the report at a hearing next week.
