President-elect Barack Obama submitted his letter of resignation from the U.S. Senate this afternoon, effective Sunday.
Obamas running mate, Vice President-elect Joe Biden, has yet to resign from his Senate seat, to which he won re-election for a seventh term on the same day he was elected vice president.
WTF does that mean?
