Tom Dering

Tom Dering was President of the United States in 1998. Dering's Vice President was Jack Michaels. He was in office when Station Nine, a top secret US space station created to destroy threatening nuclear missiles from orbit, was first used. Station Nine was used to destroy missiles headed for the USA which had been launched by Colonel Anatoli Roskov, the commander of the Nevchenka nuclear base in Krejikstan. Prior to the meeting in which he gave permission to use it, Dering did not actually know that the space station was any more than a myth.

The use of Station Nine made it visible to everyone on earth with the proper equipment. President Dering decided, with the help of his Staff Heads, to share the space station with the United Nations, stressing that it would only ever have been used in America's hands to stop a nuclear war and preserve peace. When the US and the UN received information that China was launching nuclear missiles, President Dering again authourised the use of Station Nine's own nuclear missiles. However, the information reguarding China's attack was fake, and it and the previous missile launch were actually part of a plan of the Khameirians to use a nuclear missiles power to create new bodies for themselves. Though they never interracted, the Eighth Doctor and Samantha Jones saved Dering's planet by defeating the Khameirians, and they destroying Station Nine in the process. (PROSE: Option Lock)

According to the Eighth Doctor, he served between Bill Clinton and Bruce Springsteen. (PROSE: Interference - Book One)

Behind the scenes
Dering's repeated appearances in the "present day" of the early BBC Eighth Doctor Adventures — most of which were set during Bill Clinton's real-life second term — indicate that in the DWU, Clinton lost or didn't contest his 1996 re-election bid.
