According to two people told of the decision, the campaign manager, Danny Kedem, no longer wished to oversee Mr. Weiner’s bid for New York mayor after a week of bruising revelations about the candidate’s latest online conduct. The two people, who have close ties to the campaign, did not want to be identified because they were disclosing confidential conversations.
Mr. Weiner confirmed the news on Sunday morning outside of a Brooklyn church where he was campaigning. “Danny has left the campaign. He did a remarkable job,” Mr. Weiner said.
The move suggests that even as Mr. Weiner vows to press ahead with his candidacy, there are mounting doubts about its political viability within his own campaign.
