The Kochs have been activists since the 1970s. You can go back and look at the platform of the Libertarian Party in 1980 and see what they really believe in. They wanted to abolish huge swaths of the U.S. government, including the Internal Revenue Service. They want to get rid of Social Security. They'd like to get rid of Medicare. They'd like to abolish the Environmental Protection Agency, which directly affects their business.

The Kochtopus is the nickname that people who've worked for the Kochs came up with because there's so many tentacles and it likes the shadows. I really feel the first step is to provide the information.

[Donald] Trump has put forward a list of people he would like to see on the Supreme Court, whom the Kochs would be very happy with too. So it's not all bad for them.

What these memos do is they make legal acts that were criminal prior to these memos.

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.

Barack Obama was elected President in 2008 and re-elected in 2012. The natural thing would be to suggest money on the right [wing] doesn't really matter that much. The first thing you have to know is that the presidential elections are the ones where it's most difficult for money to hold sway, in that they're the most public elections.

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.
