Republican presidential candidate Donald Trump speaks at a rally held in Ladd-Peebles stadium in Mobile
In an interview with Breitbart, Trump criticized Bush for speaking Spanish at a campaign event in Florida on Tuesday.
"I like Jeb," Trump said, according to Breitbart's Matt Boyle. "He's a nice man. But he should really set the example by speaking English while in the United States."
On Tuesday, Bush responded in Spanish to a question about Trump, saying Trump is not a true conservative.
"He attacks me every day with barbarities," Bush said in Spanish, according to The Washington Post.
"He's not conservative. He doesn't have a career that you could say is conservative," Bush later added in Spanish. "And beyond that, he personalizes everything. If you're not totally in agreement with him, you're an idiot, or stupid, or you don't have energy or 'blah blah blah.' That's what he does. That doesn't work - there are millions of people who today are thinking that their future isn't the way it should be."
When asked about Trump's comments to Breitbart, Bush's campaign directed Business Insider to a pair of tweets on Trump:

Trump has been repeatedly criticized for his controversial statements about immigrants and the Mexican government. Earlier this year, Trump faced blow-back from business partners and high profile members of the Latino community for claiming that the Mexican government was sending "rapists," drug runners, and other criminals into the United States.
The real-estate magnate was confronted by Univision journalist Jorge Ramos last week over his hard-line immigration plan, which includes a plan to deport the approximately 11 million immigrants living in the US without permission.
Trump has by far the highest unfavorability rating among Latino voters, though the real-estate mogul repeatedly insists that his plan to bring more jobs to the US will help him "win the Latino vote."
For his part, Bush has the best image with Hispanic voters among Republican candidates: 43% of Hispanics said they view him favorably, according to a new Washington Post/ABC poll.
