The latest statement from Rep. Anthony Weiner’s spokesman on the Weinergate saga makes a subtle but perhaps important rhetorical shift.

Apparently, Weiner’s office no longer uses the word “hack”; it now refers to the incident, in which a link to a lewd photograph was published on Weiner’s Twitter feed, as a “prank.”

Could that change reflect an attempt to walk back earlier “hacking” accusations?

In a possibly related development, the intended recipient of Weiner’s message (who first spoke on the record to the New York Daily News) has indicated in tweets earlier today: “Expressed my dissatisfaction to NYDN over their implication that I backed the hacking theory,” and “I do not back, nor do I doubt, any hacking theory.

These statements, plus the fact that there is no indication yet that Weiner has reported the alleged hack to authorities, suggest a new possibility: the offensive tweet may not have been a “hack,” but perhaps an inside job by someone with access to Weiner’s social networking accounts.

It is fairly standard practice in congressional offices and on congressional campaigns for multiple staffers to have access to the politician’s social networking accounts.
