Because he “has a job to do” or something.

WASHINGTON — He’s keeping his lips zipped.

Weasily Rep. Anthony Weiner said this morning he won’t talk about his bulging crotch any longer.

“After almost 11 hours of answering questions, any that anyone wanted to put today — I’m going to have to get back to work, doing the job that I am paid to do,” he said.

Weiner refused to answer any questions and walked back into his office.

On Wednesday, Weiner exposed his kinky side — finally admitting the crotch shot mysteriously sent from his Twitter account to a pretty young coed might actually be his own.

“You know, I can’t say with certitude,” he insisted when a skeptical-sounding MSNBC reporter asked, “That’s not a picture of you?”

“My system was hacked. Pictures can be manipulated, pictures can be dropped in and inserted,” Weiner said.

The hot-headed Weiner spent most of the day desperately trying to shake off the scandal, which erupted over the Memorial Day weekend, by hitting seven cable news shows, where he gave defensive answers to reporters.
