Jewish Congressman Anthony Weiner announced his resignation Thursday,following the revelation that he had sent a lewd photograph to young women online.

Instead of sending a written letter of resignation, Weiner made a televised public statement, which was met by hecklers shouting out angry remarks.

Although almost the entire Congress leadership had called upon him to step down, it was not clear what final straw convinced him to make the move.

On Monday, Weiner admitted sending a lewd photograph of his underwear-clad crotch to a young woman over Twitter and then lying about it a number of times. He refused to resign even as Democratic leader Nancy Pelosi called for a House ethics investigation.

But on Thursday he informed Pelosi and Representative Steve Israel of his intention to resign.

The last straw may have been President Barack Obama saying Weiner had "embarrassed himself," it could have been the return of his wife, Huma Abedin, from a week-long trip to Africa with her boss, Secretary of State Hillary Rodham Clinton. It might have been the plans to discuss his matter in the ethics panel, or perhaps the new photographs that popped up on the Internet showing Weiner is his college days dressed in drag.

In addition, former porn star Ginger Lee said Wednesday she has been in touch with Weiner, following him on Twitter. Although she said he didn't send her any lewd photographs, she claimed Weiner did try to steer the conversations between them in a sexual direction. Lee said she did not respond to his efforts. She also said Weiner had asked her to lie about their correspondence, and said in a press conference that he should resign "for lying to the public for a week."

Weiner, 46, has been at a treatment facility at an undisclosed location since last weekend, and has not been seen in public since telling reporters last Saturday he intended to return to work.

Some say Weiner did not really do anything to justify a resignation; he didn't cheat on his wife, and his private life is his personal business. But another New York congressman, Republican Christopher Lee, was forced to resign for much less, namely sending a photograph of his bare chest to a woman on Craigslist.
