The Kochs are very much involved in this election, not backing [Donald] Trump but backing everything down the ballot from him. They're pouring money into capturing the Senate and the House of Representatives, and state Houses across the country.

[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.

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.

Money has much more power down the ballot.

The possibility exists that the Kochs will walk away with even more power if [Donalds] Trump's defeated.

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.

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