RALEIGH, N.C. — More than a dozen demonstrators have been arrested at North Carolina's Legislative Building as part of a national movement highlighting what its organizers call injustices to the poor.

General Assembly Police Chief Martin Brock says 13 people were led away Monday in zip ties outside the offices of House Speaker Tim Moore and Senate leader Phil Berger were being charged with second-degree trespassing.

Brock says the charges came after officers responded to noise complaints. Over 150 people attending a Poor People's Campaign rally outside the building had come inside.

Police have now arrested or cited 87 people in Raleigh since weekly campaign demonstrations began May 14. Demonstrators this week focused on environmental and health care issues. They demanded Medicaid expansion, the elimination of fracking and energy entirely from renewable resources.
