MADISON, Wis. (AP) — Tommy Thompson, who was elected four times as Wisconsin governor and is wrapping up a sting as interim University of Wisconsin System president, says he’s not ruling out another run for governor.

The 80-year-old Republican told WISN-TV on Tuesday that “everything is on the table.”

Thompson said he would discuss his future with his family in April. He is resigning as interim UW president on March 18th.

Former Lt. Gov. Rebecca Kleefisch is the highest profile Republican currently running for governor. Former U.S. Senate candidates Eric Hovde and Kevin Nicholson are both also considering running.
