Nearly two dozen demonstrators were arrested Monday at legislatures in North Carolina and South Carolina as part of a national movement highlighting what organizers call injustices to the poor.

An official with the General Assembly Police in North Carolina says 13 people were led away in zip ties from outside the offices of House Speaker Tim Moore and Senate leader Phil Berger. Those arrested were charged with second-degree trespassing.

Chief Martin 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. Since weekly demonstrations began on May 14, police have either cited or arrested 87 people in Raleigh.

About a dozen people were arrested at the South Carolina Statehouse after staging a "lie-in" and blocking a highway.

Nearly two dozen people participated in the protest, calling for a "moral revival" of the health care system and an immediate expansion of Medicaid. Following the "lie-in," about a dozen demonstrators blocked U.S. Highway 1 in front of the capitol and were arrested by Columbia police. Those arrested were holding two signs, "Death Runs the Statehouse" and "Our Blood Your Hands!"

Monday's rally was the fourth in Columbia and among several held at state capitols nationwide. Demonstrators this week focused on environmental and health care issues. They demanded Medicaid expansion, the elimination of fracking and energy entirely from renewable resources.

The 40-day nonviolent national campaign will conclude in two weeks with a rally in Washington.
