He was, in my opinion, the most effectiv guy thus far!
His report from 2018 was great (not only page 294)!

He is the one who said that he would refere criminal charges against McCabe and Comey! He found the errors. He was objective and balanced (I could not be that fair, because I am biased as hell! Deathsentence biased as hell), he said that no one was willing to talk to him, until the very end!
Build on his work, ClinesmithAsshole was caught!

And everything he has presented us is now in John Durhams hands (no leaks, no nothing in the media, except smears against him and B2!) and Durham is not the only game in town!
I say, thank you Mr. Horowitz!
