The NAACP has partnered with two other advocacy groups in Colorado to bring a lawsuit against a conservative activist group known as the US Election Integrity Plan (USEIP) for allegedly going door to door in the state and aggressively canvassing and questioning voters, sometimes bearing arms. USEIP is among the organizations which advance the unfounded claim that President Biden’s victory was fraudulent. Another right-wing election integrity group, known as EchoMail, is being investigated by the House Committee on Oversight and Reform for similar practices in New Mexico.
