MADISON, Wis. (AP) — Union leaders and other protesters say they plan to make a peaceful stand when police begin clearing out the state Capitol nearly two weeks after demonstrators first occupied the building.

Police have said they will arrest anyone who refuses to clear out at 4 p.m. Sunday.

Protesters have been camping out in the building since Feb. 15 to speak out against a sweeping anti-union bill put forth by Republican Gov. Scott Walker.

Capitol police have allowed the protesters to remain, but the Department of Administration says the building needs to be cleaned.

It's unclear how many protesters plan to be arrested rather than disperse, but the number could be in the hundreds. Protest leaders say they plan to cooperate fully and are urging everyone to remain calm.
