The Senate Committee on Rules and Administration recommends technical changes in the impeachment rules adopted in 1868 for President Andrew Johnson’s trial. When impeachment of President Richard Nixon seems imminent, the committee is instructed to review those rules. Members continued their review after Nixon’s resignation, producing these recommendations. Nothing will be done with them until 1986, when they will be incorporated. They will be used in preparation for the trials of three federal judges between 1986 and 1989, and for President Bill Clinton’s 1999 trial.
