LANSING, Mich. (AP) -- Michigan State Police say they have used chemical spray on right-to-work protesters who to tried rush into the Senate chamber at the State Capitol.
Inspector Gene Adamczyk says people tried to rush past two troopers guarding the Senate door Thursday. He says the troopers used chemical spray after the people refused to obey orders to stop.
He says there were several arrests but didn't give a number.
Adamczyk says the Capitol has been temporarily closed because of concerns for the safety of people and the building. He estimated about 2,500 visitors were at the Capitol.
Adamczyk said the building wasn't at capacity but protesters were heavily concentrated in a few areas.
