RALEIGH — Nearly 20 people were arrested outside the doors of the state Senate chamber at the North Carolina General Assembly, two days after a judge struck down building rules regarding demonstrations.

Hundreds of protesters streamed into the second and third-floor rotunda of the Legislative Building Monday, taking full advantage of a ruling in Wake County Superior Court regarding rules enacted this year. The group celebrated the court decision with loud singing, chanting and shouting just before the Senate met.

The arrests during the weekly “Moral Monday” rally focused on collective bargaining and raising the minimum wage.

One protester who was arrested said she hopes state senators hear voices like hers who have to struggle to make ends meet as a single mom working at a fast-food restaurant.
