Nunes: an American hero

Representative Nunes has emerged as a hero in my humble opinion. He says Maria is the first media person even to ask him about the 70 recommendations that his Intel Committee put forth when they closed their investigation. I would vote for him for president any day. He recommends paper ballots. The committee found no collusion between Trump and the Russians, but they did find links between the Democrats and the Russians. Clinton paid for the dossier, then the FBI used the dossier to get a warrant to spy on Americans. Why is Mueller not focusing on the known collusion between Hillary, the Democrats and the DNC?
