Weiner's press conference came as one of the women came forward publicly, telling ABC News that she had traded dozens of photos and messages with the Congressman in recent weeks, including the infamous photo that he accidentally tweeted last month.
Weiner told reporters he spoke briefly with Minority Leader Nancy Pelosi before his press conference. "She was not happy," he said.
While he was considering treatment, he said he did not want to blame his behavior on any disorder or addiction. He said that he had never had a physical relationship with any of the woman involved in the story.
"I've never had sex outside my marriage," he said.
The press conference came hours after apparent photos of the Congressman surfaced on conservative blogger Andrew Breitbart's site, some of which depicted Weiner without a shirt. Breitbart claimed his source was a woman who had emailed with Weiner. In a surreal scene, Breitbart himself crashed Weiner's press conference to boast about his role in the scandal, which included posting a screengrab of the initial tweet last month that touched off the story.
Weiner's troubles began after a lewd photo was sent from his public Twitter feed to a Washington college student last month. He denied sending the picture, claiming he was hacked, but repeatedly said he couldn't say "with certitude" whether the photo depicted himself and provided few details about the nature of the apparent cyber-attack. The woman who received the tweet said in a statement she did not have a relationship with Weiner, but the Congressman told reporters on Monday he did not coach her handling of the situation. He did, however, contact her to apologize.
"I was embarrassed and I didn't want it to lead to other embarrassing things," he said of his cover-up attempt, "and it was a dumb thing to do to try to tell lies about it because it just led to more lies."
