Three suspected white supremacists arrested in Maryland and Delaware this week had discussed opening fire from different positions at Monday’s planned pro-gun rally in Richmond, Va., in the hopes of causing chaos, law-enforcement officials said.

Authorities also confirmed they arrested three other men in Georgia this week who are allegedly linked to the same violent, white-supremacist group, called “the Base,” as the men who were heading to Virginia. The Georgia men were arrested on Wednesday for plotting to murder a Georgia couple, the Floyd County, Ga., police department said Friday.
