This fellow just finished a history of Grassley’s investigation which has been ongoing for years. Grassley started seeking answers about the illegal spying on Americans done by the Obama administration long ago and got stonewalled...until now.
If you want just the facts, as Grassley has slowly gathered them, read DaveNYvii’s brilliant, concise, clear twitter expose starting with his earliest posts and working your way up to the present. Takes a lot of time and concentration. Worth it.
BTW, I posted a thread around Friday afternoon that Last Refuge virtually copied word for word, then posted today after adding a couple of pictures.
It argued that someone was feeding Nunes, Grassley, etc and that it was likely Horowitz via Sessions.
