PORTLAND, Ore. (AP) -- House Democratic Leader Nancy Pelosi is calling 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 had a telephone conversation 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 a response to Pelosi's statement.
