After admitting to lying about posting lewd photos to Twitter and engaging in inappropriate, sexually charged communications with women he met online, Rep. Anthony Weiner's political career appears to be in dire straits. Sources say he spoke with House Minority Leader Nancy Pelosi on the phone before his press conference and said he would not resign. But after the conference, Pelosi made moves to launch an ethics probe, and other Dems are now backing the investigation. Rep. Steve Israel, chairman of the Democratic Congressional Campaign Committee, called Weiner's behavior an embarrassment to "himself, his family, and the House," and said he stood behind Pelosi's inquiry. Meanwhile, a GOP source said it's important to note that Pelosi has not demanded that Weiner resign, as she did with former Rep. Chris Lee.
