UPDATED: Weiner seeks professional treatment while Pelosi, DNC chair, DCCC chair seek his resignation

UPDATE 3:20 p.m.: Rep. Anthony Weiner departed Saturday morning for "professional treatment to focus on becoming a better husband and healthier person," spokeswoman Risa Heller said. Heller's full statement, via Politico's Ben Smith:

Congressman Weiner departed this morning to seek professional treatment to focus on becoming a better husband and healthier person. In light of that, he will request a short leave of absence from the House of Representatives so that he can get evaluated and map out a course of treatment to make himself well. Congressman Weiner takes the views of his colleagues very seriously and has determined that he needs this time to get healthy and make the best decision possible for himself, his family and his constituents.

EARLIER: It's not only conservatives and who want Rep. Anthony Weiner (D-NY) to resign his congressional seat in light of his recent Twitter photo scandal: former House Speaker Nancy Pelosi (D-CA), new Democratic National Committee chairwoman Debbie Wasserman Schultz (D-FL) and Democratic Congressional Campaign Committee head Steve Israel (D-NY) have added their names to the list.

“Congressman Weiner has the love of his family, the confidence of his constituents, and the recognition that he needs help," Pelosi said in a statement. "I urge Congressman Weiner to seek that help without the pressures of being a member of Congress.”

Wasserman Schultz said of the Twittering congressman Weiner, “the behavior he has exhibited is indefensible and Representative Weiner’s continued service in Congress is untenable.”

DCCC chair Israel's statement calling for Weiner's resignation was released Saturday as well.

“Anthony’s inappropriate behavior has become an insurmountable distraction to the House and our work for the American people. With a heavy heart, I call on Anthony to resign," he said in the statement. “I pray for his family and hope that Anthony will take time to get the help he needs without the distractions and added pressures of Washington, DC.”

The scandal Weiner is in the center of began two weeks ago with a lewd photo sent from his Twitter account. Though he originally claimed the account was hacked, earlier this week Weiner admitted that he had sent the photo himself, but said that he would not resign.

Police are currently investigating private online communications Weiner had with a 17-year-old girl in Delaware.
