House Minority Leader Rep. Nancy Pelosi and Democratic Congressional Campaign Committee Chairman Rep. Steve Israel on Monday called for an ethics investigation into Anthony Weiner's online activities, which the New York Democrat said he would fully cooperate with. “I am deeply disappointed and saddened about this situation; for Anthony’s wife, Huma, his family, his staff, and his constituents,” Pelosi said in a statement. Israel called the situation “a deep personal failure” for Weiner, and said he wanted to “remove all remaining doubt” by launching an investigation. Weiner admitted Monday he had engaged in “inappropriate” online communications with at least six women, including texting and emailing lewd photos—but the congressman has refused to resign. Weiner did cancel an appearence Monday night at the Queens Pride House, where he had been scheduled to talk about how the new health-care law affects the gay community.
