From the October 15 edition of Fox News' The Kelly File:
MEGYN KELLY (HOST): They say you're going to spend $900 million on the presidential race this cycle. Is that true?
CHARLES KOCH: No, no, not even close.
KELLY: Koch says it's actually more like $300 million, and not all will go toward the presidential race. As for the Democrats' charge that the Koch's donor network is shady?
KOCH: Everything I give pretty much is public. Now, not every donor wants to or is willing to get the kind of abuse and attacks that we do, or death threats, so they're not willing to have their names out. And I think the other side is pushing for that because they want to intimidate people so they won't oppose it.
KELLY: But Charles Koch is not intimidated. And not slowing down any time soon.
