MADISON, Wis. (AP) -- The Milwaukee Police Association is re-emphasizing its support of Republican Gov. Scott Walker in the recall election.

The endorsement was made earlier this month but the union issued a response Wednesday to the statewide police union endorsing Democratic Milwaukee Mayor Tom Barrett.

That group, the Wisconsin Professional Police Association, is the largest police union in the state but it does not represent Milwaukee officers.

The Milwaukee union says it is endorsing Walker because he has shown unwavering support for safer communities.

The union has frequently clashed with Barrett over his eight years as mayor.

Most police and firefighters, including those in Milwaukee, were exempted from Walker's law effectively ending collective bargaining and forcing higher pension and health care payments from public union members.
