Rep. David Wu (D-Ore.) has officially submitted his resignation letter to Congress.

Read on the House floor during Friday's brief, 8-minute pro-forma session, the letter stated, in part, "By this letter, I give notice of my resignation from the United States House of Representatives, effective immediately.

"I shall miss this honorable work and this institution. God bless the United States of America, and God bless the House of Representatives."

The seven-term lawmaker resigned after allegations of sexual assault surfaced; a teenager left a voice mail on Wu’s district office phone accusing him of acting in a sexually aggressive manner toward her just weeks after he won reelection last year.

Oregon Gov. John Kitzhaber (D) announced on Thursday that the special election for Wu's seat will be held Jan. 31, 2012, with a primary to be held on Nov. 8 of this year.
