Weiner has informed congressional leaders he plans to seek treatment, according to Democratic insiders, and that was a factor in their decision to urge him to resign, first privately and later publicly. A coordinated effort was kicked off once Weiner decided to seek treatment, a senior Democratic aide told POLITICO. Leaders have been talking to him all week. His decision to seek treatment, on top of pressure of Sunday shows and members coming back on Monday, all equaled the ultimate decision for the leaders to go today.
