“It was pretty clear they had a different relationship than everyone else,” said one source, describing the behavior–openly flirting and largely behaving unlike Mr. Weiner was with any other staffer–as continuing into 2008, when Mr. Weiner began dating his current wife. “If you worked for Weiner, you were lucky if he refused to acknowledge your existence. Those less fortunate got called ‘cocksucker,’” said another. “So [their] rapport was exceptional.”

While relationships between staffers and their bosses–especially in the incestuous world of politics–are not unheard of, this pairing nonetheless suggests that Mr. Weiner was not completely honest when he insisted his personal proclivities were completely constrained to his private life.

“I think the notion of a member of Congress having a relationship with his staffer does not fit the bill of somebody making smart decisions about how he’s running an office and how he’s going to carry on in public life,” said one source. “It is a thing when the boss is having a relationship with a staffer and attempting to keep it a secret from anyone. That’s not appropriate and I think not something that represents smart, sound judgement.”
