William Dennison, Jr., the Postmaster-General of the United States in the Johnson Administration, resigned from his office on this day. A founder member of the Republican Party and former governor of Ohio, Dennison had been appointed by Abraham Lincoln in Spetember 1864. He told President Andrew Johnson in his letter of resignation that he supported the Fourteenth Amendment and opposed the calling of the National Union Convention in Philadelphia and therefore could no longer support Johnson's reconstruction policies. He was replaced by another Republican, Alexander Randall, former governor of Wisconsin. (By John Osborne)
