MADISON, Wis. — Police have cited more protesters as their crackdown on almost-daily sing-alongs in the Wisconsin Capitol rotunda continues.

Protesters have been singing songs complaining about Republican Gov. Scott Walker and GOP policies in the rotunda almost every noon hour for more than two years. Police launched a crackdown on them on July 24 for lacking a permit. They've issued more than 140 citations.

Walker said Monday he thinks attention to the protests is "overblown" and all the singers have to do is get a permit and they won't be interfered with.

The singers contend they don't need a permit to exercise their free speech rights. A federal judge has ruled the state can require permits for large groups.

A state Department of Administration spokeswoman says officers cited 20 singers on Monday.
