Gov. Roy Cooper has called up 550 troops from the N.C. National Guard to help with possible protests in Raleigh and the upcoming Inauguration in Washington, D.C.

Cooper mobilized 350 Guardsmen for duty in Raleigh, helping state and local police “protect the well-being of residents, property, and the right to peacefully assemble and protest,” spokesman Ford Porter said in a Wednesday news release.

The FBI sent a memo to all 50 states warning of protests between Saturday, Jan. 16 and Wednesday, Jan. 20. No specific plans to demonstrate have been announced, but a flier calling for armed marches in state capitals has circulated worldwide.
