MADISON, Wis. (WTAQ) - The state Justice Department says it will not defend former Calumet County District Attorney Ken Kratz in a federal lawsuit against him.

Stephanie Van Groll of Merrill filed the lawsuit a week after Kratz resigned in October, claiming that he violated her constitutional rights.

Kratz admitted sending 30 racy text messages to Van Groll in 2009, as he prosecuted her ex-boyfriend for domestic abuse. Once that word got out, 4 other women complained that Kratz did similar things to them.

He asked the attorney general’s office to represent him in Van Groll’s lawsuit – but Justice officials said today they would not do so.
