Conservative firebrand Andrew Breitbart revealed on Wednesday a photo that he says Rep. Anthony Weiner (D-N.Y.) took of his own genitals.

Breitbart showed the photo to the hosts of the Sirius XM radio show "Opie and Anthony" during a visit to the studio. The hosts took their own pictures of the photos and leaked them online through Twitter. Breitbart had previously said that he had explicit photos taken by Weiner but would not show them.

(The photos are available on several websites, but The Hill will not post them.)

In a statement afterward, Breitbart said that he did not mean for the photo he showed to the radio hosts to be sent out.

"Somehow, without my knowledge or permission, apparently a picture was taken of my mobile device, and subsequently published by Opie (Gregg Hughes) on Twitter," Breitbart said. "I regret that this occurred."

The photos are part of the scandal which began after Weiner tweeted a lewd picture of himself more than a week ago. On Monday the New York congressman admitted that he sent the tweet and said that he had had "inappropriate" online correspondence with six women over the last three years.

In response to Weiner's admission, House Minority Leader Nancy Pelosi (D-Calif.) and Democratic Congressional Campaign Committee Chairman Rep. Steve Israel (D-N.Y.) have both called for the House Ethics Committee to investigate Weiner for any violation of House rules.

A number of Republicans have called for Weiner to step down from his congressional seat. Former Democratic National Committee Chairman Tim Kaine has also said that Weiner should resign.

When Weiner made his announcement on Monday, he said he had no plans to step down from his seat.
