Former Florida Gov. Jeb Bush (R) said Saturday that supporters for GOP presumptive nominee Donald Trump aren’t “a bunch of idiots” and should be respected, CNN reported.

“What I fear is that people, kind of looking down their nose, will say the people that are supporting Donald Trump are a bunch of idiots. They’re not. They’re legitimately scared. They’re fearful,” Bush reportedly said at an event in Amsterdam. “They’re not as optimistic for legitimate reasons and there should be respect for that. And on the other side, a similar respect needs to be shown.”

Bush has said that he won’t support Trump as the nominee. The real estate mogul mercilessly criticized Bush on the campaign trail, calling Bush “low energy.”
