Chris Cillizza has the story:
“Congressman Weiner has the love of his family, the confidence of his constituents, and the recognition that he needs help,” said House Minority Leader Nancy Pelosi (Calif.). “I urge Congressman Weiner to seek that help without the pressures of being a Member of Congress.”
Of Weiner, Democratic National Committee Chair Debbie Wasserman Schultz (Fla.) said “the behavior he has exhibited is indefensible and Representative Weiner’s continued service in Congress is untenable.”
Democratic Congressional Campaign Committee Chairman Steve Israel (N.Y.) also called on Weiner to step aside.
That puts the top three House Democratic leaders on the record calling for Weiner to resign. If he holds out any longer, he's going to have a pretty rough time justifying himself.
Not that he doesn't already.
