With many leading Democrats calling for Anthony Weiner to resign over his controversial twittering of photos to young women, the New York Democrat's hopes that might hold onto his seat - even as he took a temporary leave of absence to receive professional treatment - may have dimmed, as more photos surfaced Sunday.
On Sunday TMZ.com published new photos it had obtained of Weiner took of himself using his Blackberry and a mirror.
CBS News has confirmed through Congressional sources that the backdrop of the pictures - which show Weiner shirtless, in a towel - is the House Members Gym, in the basement of the Rayburn House Office Building. Pictures were taken on the gym floor and in the locker room.
TMZ says the pictures were forwarded to at least one woman.
On Saturday Weiner said he would take a leave of absence from Congress to seek help, but that has not satisfied many of his colleagues, who called for him to resign. Top Congressional Democrats, such as House Minority Leader Nancy Pelosi and DNC Chair Debbie Wasserman Schultz, want Weiner to get help - but far from the Congress.
"Indefensible" is how Wasserman Schultz described Weiner's behavior.
