Anthony Weiner’s campaign manager has quit following the latest revelations that the New York City mayoral candidate continued sending racy online messages to women even after his resignation from Congress, according to The New York Times:

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. Kedem, 31, informed Mr. Weiner of his decision in the last 24 hours, the two people said.

Mr. Kedem and a spokeswoman for Mr. Weiner’s campaign declined to comment.

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.

UPDATE: The Weiner campaign has confirmed Kedem’s resignation to NY1.
