MADISON, Wis. (AP) -- Attorney General J.B. Van Hollen plans to send state Justice Department 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 says the agents and attorneys will help local election officials ensure voters comply with state election laws.

Former Democratic Attorney General Peg Lautenschlager dispatched similar teams during the 2004 election. Van Hollen sent out teams in 2008 and in 2010.

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 faces Democratic Milwaukee Mayor Tom Barrett.
