I just heard Hannity say he doesn't believe for one minute this came from Weiner. He believes this is coming out to take all eyes off of Wikileaks.
Yes; it brings a sex scandal into focus rather than Wikileaks. Although, I think things are moving so swiftly now that Hillary may be sunk no matter what happens.
I imagine in some way Obama is coordinating this and his staff came up with a twist of Weiner.
