Fire officials in La Crosse are investigating a blaze that destroyed the regional office of We Are Wisconsin, a coalition of union groups that has spent more than a $1 million dollars in the fight to recall Republican legislators.

Lt. Corey Yonkovich of the Onalaska Fire Department said Saturday night that his department spent most of the day helping La Crosse contain the fire in the 400 block of Jay St. The call came in at about 9:30 a.m. Saturday, and the building is being demolished, Yonkovich said.

'It was an older two-story building that was built in the 1800s and very difficult to get into,' he said.

Yonkovich said that a fire investigator from the La Crosse Fire Department was on the scene during the day. He said he had no idea whether the fire was caused by arson.

The building housed apartments, in addition to the We Are Wisconsin office.

One of the biggest spenders in the lead-up to the imminent recall elections, at least in the Milwaukee area, has been We Are Wisconsin, a Democratic political action committee. The La Crosse office is located in particularly hot recall territory: Sen. Dan Kapanke of La Crosse has been identified as the Republican most likely to be thrown out of office. He's being challenged in the recall election August 9 by Democratic state Rep. Jennifer Shilling.
