I believe putting the screws to Manafort is Mueller’s last straw to grab. His mission is to hang Trump. Apparently he thought he could do it or he wouldn’t have taken the assignment. Now, after more than a year he doesn’t have anything. But he can’t stop now and clear Trump so he’s trying to get Manafort to do a video affidavit reading a script of lies about Trump. He’s hoping he will crack before the midterms.
Or Mueller may have other lies he’ll spring in October. And if the rinos think Mueller has him they’ll be estatic. My hope is he was put there by God and only God can take him out.
Perhaps Manafort can learn to blink "torture" in Morse Code during the video.
