In an unusual event, Republican presidential candidates kept it civil during Thursday night’s GOP debate held in Miami.

The final four contestants – Donald Trump, Marco Rubio, Ted Cruz and John Kasich – kept away from personal insults, and instead focused on issues like immigration, Social Security and trade and tariffs, National Public Radio reports.

Another point of conversation was the controversial moment between Trump and CNN moderator Anderson Cooper, during which the Republican frontrunner told Cooper “Islam hates us.”

While Trump reportedly stood his ground, clarifying that he may not have meant all 1.6 billion Muslims, but “a lot of them,” Senator Rubio criticized the billionaire businessman for his political incorrectness.

“The problem is, presidents can’t just say anything they want,” Rubio said. “It has consequences here and around the world.”

According to NBC, the candidates also discussed climate change, with Rubio and Ohio Governor Kasich taking two different standpoints on the issue.

“Sure the climate is changing, and one of the reasons the clime is changing is because it always has been changing,” Rubio said.

Meanwhile, Kasich admitted that he does “believe we contribute to climate change,” before boasting that emissions in Ohio have been cut by 30 percent

Finally, Trump was questioned about his rallies that have been growing in violence, and gaining attention since a video of a Trump supporter punching a protestor went viral, CNN reports. The real-estate mogul answered, “we have some protesters who are bad dudes. They have done bad things,” but added that he does not condone the behavior.

Thursday night marked the last debate before Tuesday’s primaries which could cut down the number of competitors.
