Rep. Charles Rangel (D-N.Y.) is suing Speaker John Boehner (R-Ohio) and six other lawmakers, charging the ethics investigation that led to his public censure in late 2010 was mishandled. In a complaint filed Monday in federal court in Washington D.C., Rangel claims the Ethics Committee that investigated his alleged wrongdoing is guilty of “numerous flagrant, knowing and intentional violations” of his due process rights.
