Jesse Jackson Jr. resigns: Congressman submits letter of resignation to House Speaker John Boehner

WASHINGTON (AP) -- A spokesman for House Speaker John Boehner says he has received letter of resignation from Rep. Jesse Jackson Jr.

   Boehner's spokesman Michael Steel said Wednesday the Speaker's office received a letter of resignation from Jackson. Boehner's office did not immediately comment beyond acknowledging they'd received the letter.

   Jackson was easily re-elected earlier this month to a ninth term despite not having appeared in public since quietly taking medical leave in June for treatment of bipolar disorder.

   The House Ethics Committee has been looking into whether Jackson was involved in discussions about raising money for imprisoned ex-Gov. Rod Blagojevich's campaign in exchange for an appointment to President Barack Obama's vacated Senate seat.

   There also have been reports of a federal investigation into possible misuse of campaign money.
