The Bush family is not supporting Donald Trump in the 2016 election.

Dana Perino, who worked as White House Press Secretary for President George W. Bush and knows the family well, joined Bill O'Reilly on "The Factor" tonight to react.

"I think even if Jeb hadn't even been in the primary and Donald Trump would have emerged as the winner of the Republican nomination that they still would not have supported him," Perino said.

She acknowledged that she has not spoken to the Bushes specifically about this subject, but she believes they have concerns about Trump's policy, temperament, character and knowledge.

"I know that it's not about Jeb. That's what I know," Perino said.

She added that Trump also had many negative things to say about Bush 43 over the years, suggesting that he should have been impeached and that he knew about 9/11 and didn't do anything to prevent it.
