July 1, 1972:
Martha Mitchell wanted her husband to quit politics. His resignation as Nixon's campaign manager came too late to save him from prison.
John Mitchell, the former U.S. attorney general, announces his resignation as President Nixon's campaign manager. He will be replaced by former Rep. Clark MacGregor (R-MN), the chief White House adviser on congressional relations and the 1970 GOP Senate nominee against Hubert Humphrey.
Mitchell's decision comes a week after his wife, Martha, tells reporter Helen Thomas of UPI that she will leave him if he does not give up politics. It also comes, coincidentally of course, two weeks after five men, including one employed by the Committee for the Re-Election of the President -- headed by Mitchell -- are arrested in an attempt to bug the Democratic national headquarters at the Watergate office building.
