On September 8, 1974, President Ford pardoned former President Nixon for any crimes he may have committed while in office. Ford cited his authority to do so pursuant to Article II, Section 2 of the United States Constitution. He explained his reasoning in a speech to the nation which you’ll find here– http://goo.gl/JHsH4a. You can take a look at Ford’s Proclamation at https://goo.gl/tnCKFy.
There’s an excellent documentary on HBO—“Nixon by Nixon: In His Own Words.” The film delves into Nixon’s presidency, including how he purposely misled the public when he spoke about potential Supreme Court nominees. Supposedly, at least two women were under serious consideration, however, Nixon stated in a (recorded) private conversation that he wasn’t anxious to have a female on the highest court.
