David Wu, D-Ore., is once again the subject

The Oregonian report, published late Friday, cites multiple unnamed sources that a "distraught young woman" called Wu's office this spring and accused him of the encounter, which appears to have occurred over Thanksgiving 2010. When confronted, Wu said the incident was consensual. The young woman is said to be the daughter of a donor and high school friend of Wu's.

House Democratic Leader Nancy Pelosi Sunday called for an ethics panel investigation of Rep. David Wu following a published allegation that a young woman reported he'd engaged in "aggressive and unwanted sexual behavior."
The Oregon Democrat has been facing calls to resign, but remained silent Sunday over the allegation.
In a statement Sunday night, Pelolsi asked the "Ethics Committee to initiate an investigation into the allegations against Congressman Wu."
Pelosi met with Wu Saturday but neither politician disclosed any details.
The Democratic leader says she will send a letter to leaders of the Republican-led House Monday formally asking for the probe.
Wu's spokesman Erik Dorey did not return repeated phone calls for comment on Pelosi's statement.
Earlier Sunday, Dorey said he couldn't disclose what Wu did during the day or who he might have consulted.
The congressman's only response so far was a brief statement Friday that called the reports serious.
Spokesmen for both Gov. John Kitzhaber and the statewide party organization said Wu hadn't reached out to top Democrats in Oregon.
