We're at a point where Trump needs to fire Sessions and appoint a new AG. It's going to take a new AG to uncover the truth. Horowitz is good but he can't do all of the investigation of the FBI by himself. Afterall, Mueller has 13 democrat lawyers and he's been investigating Russia collusion for over a year and has nothing. There are plenty of good FBI agents waiting to testify on these crooks that were running the FBI that approved the spying on Trump's campaign. This thing is going all the way to Obama and will get Clapper and Brennan along the way. Remember that email by Susan Rice, "Obama wanted to do it by the book". Obama and his administration were so sure Hillary would win that they thought they could get away with anything and not get caught.
