>> the other great. is a hedge, right, if you don't want to give it to something politically toxic. you are not sure what will be politically toxic. few get the money, you give a charity, you physical out like, is that okay to give to them? >> exactly. so the koch brothers came out the "independent" reported they were funding this network of a climate change denying think tanks and activists. and that's why i think people are sort of skeptical at how non-transparent donor advice are. no one knows whose bank rolling was. you see the donor advice funds file a forum for all of their donors. you do ensee actually who is directing the money to go where. you just see where it end up. so i found that the donor fund she use, donated half a million to planned parenthood from 2011 to 2013 and her campaign, of course, says it doesn't implicate her money in this fund.
