WASHINGTON — After days of denials, a choked-up Rep. Anthony Weiner confessed Monday that he tweeted a photo of his bulging underpants to a young woman, and he also admitted to online exchanges with several women. He apologized for lying but said he would not resign.

"This was me doing a dumb thing and doing it repeatedly and lying about it," the 46-year-old New York Democrat said after a week of double-entendre headlines and late-night wisecracks full of Weiner jokes.
Weiner said he has had "several inappropriate conversations with women I have met online," he estimated that there had been "about six women over the past three years." He said many of the exchanges took place before his marriage, but others happened more recently.
Weiner insisted the relationships never moved beyond online interactions. "I have never met any of these women ... I've never had sex outside of my marriage."
He said he did not know the ages of all the women, but believes "they're all adults, at least to the best of my knowledge."Video: Weiner: 'I am not resigning' (on this page)
House Democratic leader Nancy Pelosi immediately called for an ethics committee investigation into whether Weiner broke House rules. "I am deeply disappointed and saddened about this situation; for Anthony's wife, Huma, his family, his staff and his constituents," Pelosi said in a statement. "I am calling for an Ethics Committee investigation to determine whether any official resources were used or any other violation of House rules occurred."
He responded by saying, "I welcome and will fully cooperate with an investigation by the House Ethics Committee."
The congressman — who was widely expected to run for mayor of New York in 2013 — said he did not feel the scandal affected his work as a lawmaker but would understand if his constituents decided not to re-elect him. "I'm going to work very hard to win back their trust," he said.
N.Y. Senator Charles Schumer said in a statement that he was "deeply pained and saddened" by the news about Weiner. "He remains a talented and committed public servant, and I pray he and his family can get through these difficult times."Video: Weiner admits to online affairs (on this page)
Weiner said he used his home computer and personal Blackberry, not government computers, in his exchanges with the women. But that may not protect him from House rules that say a member "shall conduct himself at all times in a manner that shall reflect creditably on the House."
On numerous occasions, the House ethics committee has cited that general rule in finding a representative in violation of standards of conduct.
"My wife is a remarkable woman. She's not responsible for any of this," he said. "I apologize to her very deeply."
Abedin did not attend his news conference, but Weiner said they would not be separating over the scandal.
The scandal unfolded more than a week ago when a conservative website reported that a photo of a man's crotch had been sent from Weiner's Twitter account to a college student in Seattle.
For days, Weiner claimed that he hadn't sent the photo and that he was the victim of a hacker. But he caused guffaws when he said that he couldn't say with "certitude" that the underwear shot was not a picture of him.

One photo showed Weiner on a couch with two cats nearby. The website said Weiner sent the photo using an AOL email account with the subject line "Me and the pussys."
Also, the celebrity website RadarOnline.com said a woman claimed to have 200 sexually explicit messages from Weiner through a Facebook account that Weiner no longer uses. It was not clear whether the woman who claimed to have the new photo was the person who claimed to have received the text messages.Breitbart site publishes photos of shirtless man it claims is Weiner
At Monday's news conference, Weiner said he sent the underpants photo as a joke and called it a "hugely regrettable mistake."
"I haven't told the truth and have done things I deeply regret," he said. "I brought pain to people I care about."
ABC News said Monday it planned to air an interview with a Texas woman, Meagan Broussard, who claims to be one of the women who exchanged messages with Weiner. The 26-year-old single mother said she has dozens of emails, Facebook messages and cell phone logs that document more than a month of flirting that started on April 20.
In a strange turn before Weiner's planned news conference, Breitbart took to the podium, defending the accuracy of his posts and saying his reputation was being smeared by the congressman.
He said, "This is a continuing attempt to blame the messenger ... I'm being accused of being a hacker." Added Breitbart, "I'm here for some vindication."
He later told NBC News that he made an "impromptu" decision to attend the event and considered posing as a journalist in order to ask Weiner a question. Breitbart said that when reporters started talking to him, he took the stage so all could hear.
Later pressed by reporters at the Monday afternoon event, Weiner apologized to Breitbart.
The picture showing Weiner shirtless was reminiscent of a photo of former Rep. Chris Lee, a New York Republican who abruptly resigned from office earlier this year after a shirtless photo he sent a woman on Craigslist became public.Video: Weiner: 'The picture was of me' (on this page)
Weiner married Abedin, an aide to Hillary Rodham Clinton, last July, with former President Bill Clinton officiating. Before that, Weiner had been known as one of New York's most eligible bachelors.
Weiner began his career as a legislative assistant to then-Rep. Chuck Schumer, now a senator. He was elected to the New York City Council before winning Schumer's House seat in 1998, representing parts of Brooklyn and Queens.
Earlier Monday before Weiner's public admission, New York Mayor Michael Bloomberg was asked whether the congressman could continue to effectively represent New Yorkers.
"It's always up to the constituents," Bloomberg said, adding that it was "time to get back and focus on the serious things."
The chair of the Democratic Congressional Campaign Committee (DCCC), Cong. Steve Israel issued a statement supporting Pelosi's call for an ethics committee investigation.
"Congressman Anthony Weiner engaged in a deep personal failure and inappropriate behavior that embarrassed himself, his family, and the House," he said. "Ultimately, Anthony and his constituents will make a judgment about his future."
Weiner gained a national profile during the debate over President Barack Obama's health care plan when he outspokenly professed support for a government-run "single-payer" program for everyone and later a "public option" to compete with private health insurance. He got the notice of liberals even though both proposals failed to make it into law.
