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 .

Torture is illegal, both in the U.S. and abroad. So - and that is true for the Bush administration and for any other administration.

[Donald] Trump comes along and is singing a different song. He says, "I don't need your money; I'm rich enough on my own to run." And he says, "I think we need these programs." And, lo and behold, a lot of Republican voters liked what he said.

It's hard for them to run away from their record. The Kochs are businessmen.

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.

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.

I think the scary thing is that there is in place already a sprawling infrastructure of advocacy groups, think tanks, academics and candidates and politicians funded by the Kochs and other deep-pocketed groups on the far right ready to attack Hillary Clinton.
