U.S. lawmaker Anthony Weiner is reportedly resigning from the House of Representatives following his involvement in an Internet sex scandal.

U.S. media report the married Democrat from New York will announce his decision to step down Thursday.

House Democratic Minority Leader Nancy Pelosi declined to take reporters' questions on Weiner Thursday, saying she would not talk about the issue before his announcement.

Weiner has admitted to exchanging explicit photographs and messages with six women during the past three years.

On Monday, the House approved a two-week leave of absence for Weiner so he could seek professional help.

His indiscretions became public late last month when a lewd photo sent to a female college student showed up on his Twitter feed.

Weiner initially claimed his account had been hacked. But more than a week later, the 46-year-old congressman held an emotional news conference, admitting the photo was his and that he had sent it.

He apologized for lying, but rejected numerous calls for his resignation. Even U.S. President Barack Obama voiced his opinion, telling NBC News that he would step down if he were Weiner, and calling the congressman's behavior “highly inappropriate.”

Weiner's wife of nearly one year, Huma Abedin, is a long-time aide to Secretary of State Hillary Clinton. Last week, The New York Times reported that Abedin is pregnant with the couple's first child.

Weiner said he never met any of the women he corresponded with online and by phone and that he was not sure of their ages. One woman who has spoken out about her online relationship with Weiner is a former porn star. The congressman also corresponded with a 17-year-old girl, but local authorities found nothing inappropriate in those exchanges.

Minority Leader Pelosi called for an ethics investigation to determine whether Weiner used any official resources in his communications or if any other violation of House rules occurred. Pelosi has said Weiner needs help and he should get some “without the pressures of being a member of Congress.”

Weiner says he did not break the law.
