Richard Nixon

Richard Milhous Nixon was the 37th President of the United States.

Biography
In 1969, Nixon received a number of calls direct to his office. Unsure of who was calling him in a plea for help, Nixon had Canton Everett Delaware III brought in. He had FBI, but was no longer on the service, making him perfect for Nixon's task.

Nixon showed Canton a playback of one of the calls. He then found the Eleventh Doctor in his office and called security. They promptly overwhelmed him. However, with Nixon's permission, the Doctor was allowed to help solve the mystery of the calls.

He worked out the caller's location just as Nixon received another call. He informed the caller that he had sent his best men: the Doctor, Amy Pond, Rory Williams and Canton. (DW: The Impossible Astronaut)
