There are some areas where the Kochs are on the same page with [Donald] Trump. He doesn't believe in global warming. He says it's a hoax .

David and Charles Koch are pretty much as far right as you can get on the ideological spectrum without falling off. They are far right libertarians, very anti-government, very pro-business, very anti-tax, anti-regulatory, in favour of free markets ruling the day.

[The Kochs] they hate big government.

Ethically, I think pretty much every code of ethics for doctors suggests that they should not be in an interrogation room, particularly if there's anything coercive or abusive going on.

And to me, it was interesting, some of the people I had interviewed who knew the insides to this program said that they also, to create anxiety and upset in the soldiers, they take Bibles and they trash them.

In fact, Charles Koch tried to get [Mike] Pence to run for the White House in 2012.

So you've got these regular, middle-class voters who don't hate the government as much as the Kochs do. They're Republicans, but they still want government programs. They want Social Security, they want Medicare. They need it.
