Haley finally gets a question on foreign policy, a strong suit for the former U.N. Ambassador. She defends American support for Ukraine and ties it to the fight against China. But while the moderators teed her up to attack DeSantis, she instead pivots to Ramaswamy. She's pretty fiery in her back-and-forth with him, saying he has no foreign policy experience "and it shows."

On Russia's invasion of Ukraine, Christie referenced his recent trip to the war-torn country and said that he "wanted to see for myself what [Russian President] Vladimir Putin's army was doing to the free Ukrainian people."

"They have gouged out people's eyes, cut off their ears and shot people in the back of the head," Christie said of the brutality he saw.

"This is the Vladimir Putin who Donald Trump called 'brilliant' and a 'genius,'" he continued. "If we don't stand up against this type of autocratic killing, we will be next."

Born in 1985 and only 38, Ramaswamy may be the only candidate on stage who was too young to remember the Cold War. The USSR dissolved when he was 6.

The debate over Ukraine is a window into the intraparty battle between its previously more dominant neoconservative wing that lost credibility during and after the George W. Bush years and the comparably isolationist wing that's gained ground with Trump's time in office. Ramaswamy, as an avatar for the New Right, specifically name-checked the Iraq War, saying the Ukraine conflict could lead to American intervention. By comparison, Pence and Haley, more traditional conservatives who have foreign policy experience from their time as vice president and U.N. ambassador, respectively, were especially vocal in defending U.S. support for Ukraine.-Analysis by Geoffrey Skelley of FiveThirtyEight

At PolitiFact, this is our fifth presidential cycle. We’ve published more than 23,000 fact-checks since launching in 2007, all using our Truth-O-Meter, which rates claims on a scale from True to Pants on Fire false for the most ridiculous claims.

If PolitiFact is new to you, there are a couple of rules of the road.

First, we don’t fact-check every claim every candidate says. We couldn’t … we’d be dead.

We focus on claims that are particularly interesting, in the news or obviously potentially wrong. Our grading scale tries to measure both the literal truth and how voters might interpret a politicians’ words. So if Pence tonight claims that he and Trump “achieved energy independence” in their first three years in office, it can be more complicated to fact-check than you think.

In Pence’s case, yes, the United States did produce more energy than its citizens consumed during the Trump/Pence White House, but that was built on more than a decade of improvements in shale oil and gas production, as well as renewables. And the U.S. did not produce more gasoline than it consumed (which is maybe what you were thinking about). And if that’s not enough, even though the U.S. didn’t use all the energy it produced, it still imported a substantial amount of energy to serve domestic markets.

So far in this cycle, we’ve published 52 fact-checks of the GOP candidates. Our checks tend to follow the polling of the race. We’ve fact-checked Trump 17 times, DeSantis 14 times, Pence six times, Haley and Tim Scott each five times, and so on. We'll be drawing on those previous fact-checks, as well as the thousands of other claims we've vetted, throughout the night.
