The first Republican debate of the 2024 presidential primary was held in Milwaukee on Wednesday night.

Eight candidates qualified for a spot on the stage: North Dakota Gov. Doug Burgum, former New Jersey Gov. Chris Christie, Florida Gov. Ron DeSantis, former U.N. Ambassador Nikki Haley, former Arkansas Gov. Asa Hutchinson, former Vice President Mike Pence, entrepreneur Vivek Ramaswamy and South Carolina Sen. Tim Scott.

Missing from the event was the primary's early front-runner: former President Donald Trump, who declined to participate and instead released a pre-recorded interview with Tucker Carlson.

ABC News and FiveThirtyEight live-blogged every major moment and highlight from the debate, aired on Fox News, with FiveThirtyEight providing analysis and a closer look at the polling and data behind the politicians. PolitiFact made real-time fact checks of key statements.

Martha MacCallum just asked about what to do about migrants already in the United States. In a July poll by The New York Times/Siena College, 39 percent of likely Republican voters say that they supported a “comprehensive immigration reform bill that provides a pathway to citizenship for all undocumented immigrants” in the United States, while 57 percent opposed such a bill. Support was weakest among Trump supporters (29 percent) compared with DeSantis supporters (48 percent) and voters who say they will vote for another candidate (50 percent).

Sen. Scott so far has stayed away from attacks and stuck to his stump speech

While many candidates onstage have sparred with each other -- including Haley and Ramaswamy swapping sharp words on foreign policy -- Scott has yet to engage with any of the other candidates.

Much of his remarks have almost word for word repeated elements from his campaign stump speech. When asked about China, which he has addressed in other appearances, he pivoted to speaking about the U.S. border.

DeSantis said he wouldn’t increase aid to Ukraine: "Europe needs to step up"

Asked to raise their hand if they would not increase aid to Ukraine, DeSantis did so, saying that "Europe needs to step up. They need to step up and do their job."

He argued: "I would have Europe pull their weight. ... Our support should be contingent on them doing it.

DeSantis -- who had received backlash from some other politicians for seemingly backtracking on support for Ukraine -- pivoted to say that he wasn’t going to send troops overseas but rather down to the Southern border.
