MSNBC reports that:
"Rep. Anthony Weiner [D-NY] said Wednesday that he can't say 'with certitude' whether or not a lewd below-the-belt photo depicted his body, but he insisted that he did not tweet the picture to a 21-year old college student in Seattle, Wash."
Weiner also said he's hired a private security firm to look into what he says was a hacking of his Twitter account and the sending of the photo.
The congressman is doing a series of interviews with the news media this afternoon. We'll update with developments.
