Richard Nixon

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

Biography
In 1969, Nixon received a number of calls directly to his office, wherever he was. Unsure of who was calling him in a plea for help, and suspecting FBI involvement, Nixon had Canton Delaware brought in. Having been in the FBI, but no longer in service, he was perfect for Nixon's task.

In the Oval Office at the White House, 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)
