Here's a look at some of the key moments making headlines in the Republican debate:
- Kasich vs. Trump on immigration: They got into it after Trump again talked about his plans for a wall and mass deportations, notes Politico. "It’s a silly argument," said Kasich. "It’s not an adult argument. We all know you can’t pick them up and ship them back across the border." Trump then took a shot at Ohio's recovery, where Kasich is governor: "You’re lucky in Ohio that you struck oil," he said. Later, as Kasich tried to talk over him, he added, "I don't have to hear from this man."
- Trump disses Fiorina: After Fiorina sought to jump into a conversation, Trump asked, "Why is she always interrupting everyone?" The remark drew boos from the audience and this from Nicholas Confessore at the New York Times: "Donald Trump complaining about somebody interrupting him is, well, quite something for anyone who has watched these debates."
- Rubio vs. Rand on military: The two sparred when Paul accused Rubio of abandoning conservative principles with plans for big military spending, reports the Washington Post. “I know that Rand is a committed isolationist,” said Rubio. “I’m not. I believe the world is a safer and a better place when the United States is the strongest country in the world.” Paul then responded: “You cannot be a conservative if you're going to keep promoting programs that you're not going to pay for."
- Foreign policy disagreements: In what the Post calls "one of the most substantive exchanges of any Republican debate so far," the candidates went back and forth about the US role in the world, making clear that big differences exist within the party. Trump and Paul called for restraint, for example, while Fiorina and Bush pushed for a more aggressive policy. At one point, Trump talked about meeting Putin, while Rubio called him a "gangster."
- Bush fights for time: “You’ve already made your comment, it’s my turn, John … I got about four minutes last debate—I’m gonna get my question now," said Bush to Kasich. The Ohio governor responded, "I appreciate it, Jeb, I'm all for you," but continued to speak over him. Later, in his own spat with Kasich, Trump, said, "You should let Jeb speak." Bush responded sarcastically, "Thank you, Donald, for letting me speak."
- Ben Carson said he didn't mind being vetted, but he did object to "being lied about." That and other big lines, including a Ted Cruz flub, are here.
