Donald Trump actually is a pretty big-government conservative. He doesn't see eye-to-eye with them [the Kochs] on trade.

The idea is that if we can put our own people through something almost as bad as what they might have to go through if they were taken captive, they will inoculate themselves.

What I write about is how much influence it's had in things like state legislatures and governorships and congressional races. The other thing that's even more important in the long run is that very extreme money has affected the ecosystem of ideology in the country.

[Tom] Steyer is specifically spending money on candidates who will take action against climate change.

The book that I wrote is called Dark Money, and it's about secret spending that is very hard to follow. [George] Soros's whole thing is about government transparency, so he spends very much in the open, and the same with [Tom] Steyer.

The concern that I have is that, as wealth continues to concentrate in the hands of a few, economic inequality grows, and power also becomes more unequal.

One of the oddities of this election is the man that [Donald] Trump chose as his vice-president, Mike Pence, is one of the Kochs' favourite politicians.
