Hillary Clinton's campaign has responded to a recent ABC News interview with billionaire Charles Koch, in which the GOP donor suggested he might prefer Clinton over the remaining Republican candidates.

"Not interested in endorsements from people who deny climate science and try to make it harder for people to vote," the campaign tweeted on Clinton's account.





In an interview that aired today on ABC News' "This Week," Koch said Clinton's husband former President Bill Clinton was "in many ways" a better president than President George W. Bush.

When asked whether another Clinton presidency would be preferable to a Republican one, given those who are left in the GOP primary field, Koch replied, "It's possible."

However, Koch acknowledged he wasn't yet putting himself down as a Clinton supporter.

"We would have to believe her actions would be quite different than her rhetoric. Let me put it that way," he said.
