With the NAACP as counsel, Rep. Bennie Thompson (D-Miss.) on Tuesday sued the former president, his lawyer Rudolph W. Giuliani, the Proud Boys and the Oath Keepers, accusing them of conspiring to stage the Capitol insurrection and violating a law known as the Ku Klux Klan Act. The complaint explains that the law, enacted in 1871, “was intended to protect against conspiracies, through violence and intimidation, that sought to prevent Members of Congress from discharging their official duties. The statute was enacted in response to violence and intimidation in which the Ku Klux Klan and other organizations were engaged during that time period.”
