The younger Biden has released a statement as his unit prepares to deploy to Iraq. Beau Biden says he hasn't sought and wouldn't accept an appointment to the Senate, and that he looks forward to returning to his job as attorney general after his service tour.
Biden was seen as a possible successor to his father, Democrat Joe Biden, who must resign his Senate seat before being sworn in Jan. 20 as vice president. Delaware's governor will appoint a new senator.
Speculation on Biden's replacement has centered on Lt. Gov. John Carney. He lost the Democratic gubernatorial primary in September to State Treasurer Jack Markell, who is now Delaware's governor-elect.
