Mensch has been spot on so far, and way ahead of the MSM who have been openly sceptical about her reporting. I agree she's generally a big PITA and can be pretty nasty, but on this I have to give her credit.
This, though, seems extraordinary. Claude Taylor is also reporting it and again, he has been accurate so far. So let's hope it's true.
A little bit of doubt tells me that as the stakes rise, these sources may get duped. I hope not.
