Fast-forward through to the part where Robert Costa comes on to discuss Trump's operation with Rachel Maddow.

At about six minutes in, Rachel asks Costa Trump's campaign staff seems savvy, like they know what they're doing.

"I think one of the most underreported parts of this campaign is it comes out of the Koch brothers' network," Costa replied.

He continued, "Trump's campaign manager came directly from being a grassroots organizer, national voter registration guy for the Koch brothers...for Americans for Prosperity."

"He was working in New Hampshire for AFP. He comes right out of there to work for Trump. If you look at Trump's Iowa network, New Hampshire, it's full of AFP people."

Now why would that be? Surely the Kochs wouldn't want Trump to be the final nominee? Or would they?
