At a press conference on Monday, Rep. Anthony Weiner, D-NY admitted that one of the women whom he had corresponded with online was Megan Broussard, 26, a single mother from Texas.

Her revelation of a phone call said to have been made from his office to her may have bearing on whether a Congressional ethics probe is launched, a move which House Democrat leader Nancy Pelosi has called for.

Weiner on Monday admitted to lying about a lewd photo tweet scandal for more than a week, saying he had indeed sent a bulging underwear crotch photo of himself to a 21-year old woman in Seattle by mistake, deleted it and then claimed he had been hacked. He also admitted to having frivolous and inappropriate online relationships with 6 other women in which he sent explicit photos.

However Weiner also denied breaking any ethics rule or law and said he would not resign from his post.

Broussard released dozens of photos, email messages, Facebook messages and cell phone log calls that she says show a sexually-related communications with Weiner starting from April 20, 2011, according to ABC News.

One revelation by Broussard may have implications for a Congressional ethics probe, if one is launched. Broussard said she believes Weiner used his New York Congressional office phone to contact her in the one and only time they spoke by phone.

Broussard told ABC a man identifying himself as the Congressman called her from a number linked to the office.

She says the call took place on the afternoon of May 18.

The day he called he just said, 'Who in the world would be acting like me?' laughing about it, Broussard, who is a single mother said.

After hanging up, Broussard said she called the number to see if it was Weiner. A receptionist at the congressman's office answered, she said. ABC news says Broussard provided the news organization with a record of the call.

House minority leader Nancy Pelosi, D-CA on Monday called for an ethics investigation to determine if official resources were used.

I am deeply disappointed and saddened about this situation; for Anthony's wife, Huma, his family, his staff and his constituents, House Minority Leader Nancy Pelosi (D-Calif.) said in a released 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.

Weiner said he did not admit the relationships to constituents and the media because he was embarrassed and I didn't want it to lead to more embarrassing lies.
