MADISON, Wis. -

Attorney General J.B. Van Hollen plans to dispatch criminal investigators and lawyers to the polls during Tuesday's recall elections to discourage fraud.

Van Hollen, a Republican, plans to deploy teams of special agents and assistant attorney generals across the state, including dispersing seven groups to the polls in Democratic-leaning Milwaukee. He said the agents and attorneys will help local election officials ensure voters comply with state election laws.

Van Hollen dispatched similar teams to the polls in the 2004, 2008, and 2010 general elections.

Democrats upset with Republican Gov. Scott Walker's contentious plan that all but ended collective bargaining for most public worker forced the governor and four other GOP officeholders into Tuesday's recalls. Walker will face Democratic Milwaukee Mayor Tom Barrett.
