Former Florida Gov. Jeb Bush took a shot at fellow GOP presidential candidate Donald Trump for bullying other GOP candidates in the 2016 race.

"Donald Trump is trying to insult his way to the presidency," Bush on ABC Thursday morning. "[Trump's] comments are hurtful to a lot of people, and Mr. Trump knows this. People want a hopeful, uplifting message."

The comments by Bush are the latest in a back-and-forth between the two Republican presidential hopefuls. Trump on Tuesday said Bush should "set the example" by speaking only English and not Spanish when in the United States.

"[The fact] that he would say we should only speak English is kind of ridiculous if you think about it," Bush said of Trump, the current GOP front-runner. "We're going to close all the foreign language classes? Why would he have a contract with Univision for his beauty pageant? This is a diverse country, we should celebrate that diversity and embrace the set of shared values."

Bush added: "Mr. Trump doesn't believe in those shared values."

Trump currently leads the Republican field in multiple national polls, including a RealClearPolitics average with with 26.5 percent. Bush garners 9.5 percent.

Despite the bickering, Bush said he would support Trump should he become the eventual nominee, a question Trump has not answered.

"Yeah I would — of course," Bush said. "We need to be unified. We need to win."
