Hawks, Sessions doesn't have the authority to end the investigation. He's already recused himself. Trump can end it whenever he wants. He can fire Rosenstein whenever he wants. The political fall-out would be devastating, so instead, he whines about it like a little bitch on Twitter. Huckabee Sanders, bless her lying heart, is probably right on this one. Trump, in his infinite stupidity, was probably just stating his opinion. One, I'm sure, Mueller will be looking at for possible obstruction, but probably just another moronic Trump opinion.
