To be clear, none of this means the Africa story is false -- just that it didn't come from this source. Martin Eisenstadt was not one of Fox News correspondent Carl Cameron's sources.

Fox News won't be retracting Carl Cameron's original report about the Palin/Africa flap, because it did not come from Eisenstadt — which the filmmakers confirmed to TVNewser Thursday:

"To be very clear, no, we were not the source for Carl Cameron and never spoke to him," Mirvish tells TVNewser. "We took credit for his anonymous sourcing. If they were going to be cowards, then we figured we may as well step in."
