MADISON, WI (WTAQ) - The state Democratic Party will no longer use Graeme Zielinski as its chief spokesman, after he compared Governor Scott Walker to Milwaukee serial killer Jeffrey Dahmer.

The comments were made on Twitter last Friday, after prosecutors said they ended a John Doe investigation into Walker’s former Milwaukee County aides.

Walker himself was not charged – and some Democrats criticized that outcome, with one Democratic leader even asking Walker to apologize that the investigation had to take place.

Zielinski later apologized on Twitter both to Walker and to Dahmer’s murder victims.

Zielinski lost a week’s pay of just over a-thousand dollars. He’ll stay with the Democrats as a media adviser, but he won’t be able to speak for the party on Twitter.
