Conservative website posts private pictures of Anthony Weiner

Updated 12 p.m. ET

Conservative activist and author Andrew Breitbart on Monday posted two pictures of Democratic Rep. Anthony Weiner, which Breitbart alleges were emailed to a young woman he declined to identify.

A spokesman for Weiner did not immediately respond to a request to confirm that Weiner had, in fact, sent the photos. Breitbart has promised to post more photos of Weiner later Monday.

The first picture -- posted on biggovernment.com and bigjournalism.com (two websites run by Breitbart) -- shows Weiner holding up a piece of white paper with the word "me" and an arrow pointing to Weiner's face. Breitbart alleges Weiner took the photo of himself to prove to a woman with whom he was corresponding that he was in fact, the Anthony Weiner who represents New York City in Congress.

Breitbart also a posted a picture of Weiner with two house cats in the background. Breitbart says Weiner sent the photo of the cats using an anthonyweiner@aol.com email account with a subject heading "Me and the pussys."

Weiner last week came under fire for a photo of a bulging crotch in grey underwear that was sent from his Twitter account. Weiner has said the photo was a prank, or that his Twitter account was hacked. He said he could not say with certainty whether or not the photo was in fact him.
