Congressman Anthony Weiner, D-NY again said Thursday he would not resign, after his Monday admission to sending a photo of his bulging crotch in underwear to his 45,000 Twitter followers and then lying about it for more than a week.

I'm not, he said in response to a New York Post reporter's question on whether he planned to resign. I'm going to get back to work as best as I can.

Anthony admitted he betrayed a lot of people including his constituents and family.

I was completely honest on Monday after I hadn't been for a while, Weiner said while visiting his lawyer's office in Midtown Manhattan.

Weiner, 46, is fighting for his political life as Congressional leaders have isolated him, with Republicans calling for his ouster. Democrats had held fire since the Monday's. However on Wednesday Rep. Allyson Schwartz, D-PA became the first Democrat to call for his ouster.

House Republican Leader Eric Anthony, R-VA, called on his colleague on Tuesday to resign, saying Congress has a lot of work to do.

The last thing we need is to be immersed in discussion about Congressman Weiner and his Twitter activities, he said.

House Senate Leader Harry Reid said he wouldn't even give Weiner advice on Tuesday, saying if Weiner asked, Reid would tell him to call somebody else.

Also on Tuesday, House Democratic Leader Nancy Pelosi formally requested an ethics probe to determine whether any official resources were used.
