Sussmann is desperate and playing with fire. Cooper did Sussmann a favor by excluding certain evidence, but leaving the door cracked if the defense crossed the line, and this filing absolutely crosses it, by producing these mysterious handwritten notes that evidently the FBI/DOJ had no access to or Durham would already have them. The origin of these notes remain to be seen. The fact that McCabe is attached to them, is shady, and the fact that these notes are being represented as taken during official interviews makes them work product that somehow walked out of the FBI makes them evidence of a felony committed by them leaving the agency. McCabe has already lied under oath to the Senate that's well documented if he becomes a witness for the defense his impeachability for truthfulness is high. But if cooper allows these notes to be introduced to the jury, Katie bar the door on the mountain of crap Durham can bring.
