Via Graham Linehan, the USA gets its first atheist member of Congress, Pete Stark of California:

Stark, who is a Unitarian, is the highest-ranking American politician to openly declare that he is nontheist. Although Stark denies a belief in a god, he was quick to note that the Stark family does recognize a supreme being: Mrs. Stark.

Though it does help to confirm my belief that a Unitarian is just an atheist who likes to go to church.
