This much we know. Over Memorial Day weekend, someone used U.S. Rep. Anthony Weiner's Twitter account to publish a photo of an underwear-clad male crotch apparently in a sexually excited state.

The New York Democrat denies posting the photo, claiming that his Twitter account was hacked, but he has deflected persistent inquiries into whether he is the owner of the offending (apparent) genitalia.
