Just weeks after Anthony Weiner resigned from Congress following a sex scandal, Oregon Rep. David Wu is stepping down amid allegations involving a teenager.
A distraught 18-year-old woman called Wu’s Portland, Ore., office, accusing the politician of aggressive and unwanted sexual behavior. The woman is the daughter of a longtime friend of Wu, according to The Oregonian.
“This is very serious, and I have absolutely no desire to bring unwanted publicity, attention, or stress to a young woman and her family,” Wu, 56, says in a statement to the newspaper.
Following a House ethics investigation after initial reports of the allegation, Wu announced that he is resigning.
