Fox never claimed to get this tape, so I think the story is just a story by the API.
Why is the API playing with make believe stories?
My theory: the original story was fabricated, either by Korir or one of his stringers, and they were caught by surprise when the story, which normally would have been read by his couple of hundred Africans in Norway readership, went viral. At that point, he has to either 'fess up or dig in and hope for it to go away. He's done the latter. If he can stall until next Tuesday, he figures no one will care anymore, or he'll come up with some other story about why he's permanently sealing the tape or somesuch. I'll put money on this.
I have a couple different theories.
Two of them revolve around obama traps for conservatives and “fox news”. Trying to discredit both.
Other, it’s true? (I’m not convinced)
or, you can’t sue anybody in Norway.
