Weiner admitted to exchanging racy photos and having X-rated chats with a woman he met online. He had resigned his Congressional seat in June 2011 after acknowledging having sexual conversations with at least a half-dozen women.

Weiner reiterated at a news conference that he put such behavior behind him before deciding to run for mayor. His wife, Huma Abedin, stood by him, saying Weiner "made some horrible mistakes," but that she has forgiven him and believes in him.

The newly revealed correspondence was posted Monday by the gossip website The Dirty. The woman involved was not identified. She says their online relationship began in July 2012 and lasted for six months.

The married ex-congressman had predicted more texts and photos might come out. Since re-entering public life this spring, he has apologized repeatedly for his behavior. He also has been near the top of most mayoral polls since entering the race.
