SALEM, Ore. – Voters in Oregon's first congressional district will have to wait until next January to find out who will succeed David Wu. The disgraced Congressman officially resigned Wednesday night.

Oregon Governor John Kitzhaber scheduled a special primary on November 8th. That will be followed by a special election January 31st. A week after announcing he'd leave office, Wu officially turned in his resignation just before 9 o'clock Wednesday night. The Democrat left in the middle of his seventh term after reports of an alleged sexual assault of an 18-year-old daughter of a campaign donor. Wu never denied the allegations and faced intense pressure to step down. Earlier in the year, Wu faced questions about a mass exodus of staff members and reports of erratic behavior.

It may be a relatively short campaign season, but the chance to win an open seat in Congress is drawing plenty of candidates. Wu's Republican opponent in last year's election, Rob Cornilles, is set to enter the race. Several Democrats are also running.
