Richard Nixon

Richard Milhous Nixon was the President of the United States from 1969 to 1974 (TV: The Impossible Astronaut, COMIC: Before the Flood). The Eleventh Doctor was not particularly fond of him due to the unfortunate events that happened during his term as president, such as Vietnam and Watergate, but soon got over it. Nixon assisted the Doctor during his investigation of the Silence, often using his power as president to do so; he freed the Doctor after he was arrested and calmed down soldiers at Area 51 by giving a speech.

In 1969, Nixon received calls directly to him, wherever he was, from a child telling him she was scared of the monsters that were everywhere and that an astronaut was coming to eat her. (WC: Prequel (The Impossible Astronaut))

Nixon asked the child where and who she was, mistaking the location she was giving, "Jefferson, Adams, Hamilton", as her name and also mistaking her for a boy. However, she hung up befor he could learn more. Unsure of how or why the child was calling him, and suspecting FBI involvement, Nixon had Canton Everett Delaware III brought in. Having been recently fired from the FBI, he was the second best choice for Nixon's task; he had the training needed, but wasn't with the Bureau.

At the White House, Nixon played Canton a recording of one of the calls. He found the Doctor writing down their conversation in his office and called security. They promptly overwhelmed the Doctor until River unveiled his invisible TARDIS and the Doctor came up with the alibi that he was on loan from Scotland Yard, sent to also help him with the case. Nixon allowed the Doctor to help, along with his companions, giving him whatever he needed to find the mysterious caller.

The Doctor worked out the caller's location from the names she had given Nixon and when Nixon received another call, he informed the caller that he had sent his best people to help: the Doctor, River Song, Amy Pond, Rory Williams, and Canton. As they left to go find the little girl, Nixon watched the TARDIS dematerialise from sight, leaving him shocked. (TV: The Impossible Astronaut)

Three months later, Nixon came to the Doctor's rescue when he was detained by NASA security after implanting an extra device of his own into the on-board computer for Apollo 11. After travelling in the TARDIS to Area 51, he calmed the security team after Canton had spent days "inside" the prison. In the White House after the Silence threat had been eliminated, he asked the Doctor about his future. The Doctor said that he would always be remembered, and told him to say "hi" to David Frost for him. At the Doctor's urging, Nixon tried to be lenient and allow Canton to get married, believing he wished to marry a black woman. When Canton revealed he wished to marry a black man, Nixon was taken aback. Regaining his composure, he told Canton that "I believe the moon is far enough for now." (TV: Day of the Moon)

Nixon's recordings, referred to as the Nixon Tapes, were left for future presidents to know of the Doctor. (COMIC: Air Force Gone)

In the 1970s, President Nixon was involved in the Watergate scandal. (PROSE: Dancing the Code, TV: The Impossible Astronaut)

In 1974, he authorised the "omega solution", the complete nuclear obliteration of Great Britain, in order to stop the invasion of the Remoraxians. The attack was called off by the CIA when the Remoraxians left. (COMIC: In With the Tide)
