This is entirely relevant to doing that Frank!
How so? We have enough to work with already with the people involved in this Russia fiasco. Dragging some ex FBI guy out claiming McCabe told him to water a report down isn't going to do squat with moving the ball forward on Mueller. It WILL polarize people because the Benghazi dust up is a loser. It's been politicized all to hell.
Benghazi along with all the other GOP White Whales like Obama's nationality, Ft Marcy Park, Whitewater never get anything done. Every time old stuff is brought up people tune it out. When something is fresh, people get outraged. That is why Donny is going to skate on the woman abuse stuff and everyone accused from now on is going through the grinder. The hearings today over the Russian fake report were grand. That stuff is going to make headway with voters in shaping opinions on how corrupt Mueller is. Some old fart talking about a years old report is not.
