If I were Hillary Clinton, I would have accepted the endorsement -- and still pointed out where the Koch Brothers are wrong. If they still endorse you after you do that, you're definitely better than what the Republicans are offering.
Hillary Clinton REJECTS support from multi-billionaire Republican donor Charles Koch, saying she's 'not interested in endorsements from people who deny climate science'
"In a scathing attack on Trump and Cruz, Mr Koch said he could not back either candidate unless they backtracked on some of their controversial policies.
The businessman singled out Cruz's vow to carpet bomb ISIS in the Middle East and Trump's ban on Muslim immigrants as policies he could not support.
'That's gotta be hyperbole, but I mean that a candidate - whether they believe it or not - would think that appeals to the American people. This is frightening,' Mr Koch said."
I agree -- and I've never said that before about anything the Koch brothers have said.
