MADISON, Wis. (AP) — The Whitnall School Board is notifying parents that if former superintendent and current state superintendent candidate Lowell Holtz comes under investigation, the board will cooperate. The board sent parents a letter on Wednesday saying that another group had requested the Milwaukee County district attorney investigate Holtz. If contacted, the board says it will cooperate. But the letter signed by the board says it will not spend any money on its own trying to recoup wages from Holtz for the time he may have used district resources sending campaign-related emails while working for the district. Holtz has denied he did anything wrong. He retired from Whitnall last year to run for state superintendent. He is challenging incumbent Tony Evers in Tuesday’s election. They meet Friday night for a debate broadcast statewide.
