A distraught young woman called U.S. Rep. David Wu's Portland office this spring, accusing him of an unwanted sexual encounter, according to multiple sources.Wu, like Anthony Weiner last month, was facing increasingly tough re-election prospects and diminishing support from his own party, leading to Tuesday's announcement.
When confronted, the Oregon Democrat acknowledged a sexual encounter to his senior aides but insisted it was consensual, the sources said.
The woman is the daughter of a longtime friend and campaign donor. She apparently did not contact police at the time.
One person who heard the voice mail described the woman as upset, breathing heavily and "distraught."
In the voice mail, the young woman accused Wu of aggressive and unwanted sexual behavior, according to sources with direct knowledge of the message and its contents.
Reporters could not verify the young woman's age. Notes on Facebook over the past 18 months indicate she graduated from high school in 2010. California records show she registered to vote in August.
The sexual misconduct allegations come a few months after campaign and Congressional staffers resigned from Wu's office after the Portland congressman displayed increasingly erratic behavior.
