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.

Haley gets cheers when striking back at Ramaswamy on Israel

Ramaswamy and Haley traded shots on his Israel and Russia-Ukraine views, with Ramaswamy interrupting Haley and claiming she has been saying misleading things about his proposals on Israel. Ramaswamy has called for winding down aid to Israel after integrating the country more into the region.

"I wish you well on your future career on the boards of Lockheed and Raytheon,” Ramaswamy quipped, referring to the aerospace and defense companies.

Haley struck back: "You have no foreign policy experience and it shows," she said -- and was met with cheers and applause from the audience.

Trump, in Tucker Carlson interview, says other GOP candidates shouldn't be running

Trump wasted no time attacking other Republican candidates during his pre-taped interview with former Fox News host Carlson.

"I'm saying, do I sit there for an hour or two hours, whatever it's going to be and get harassed by people that shouldn't even be running for president?" Trump said.

The 46-minute interview -- released on Carlson's X account as the GOP debate got underway -- is being seen among the campaigns as an attempt to counter-program the first debate among 2024 Republican presidential candidates on Fox News.

DeSantis again vows to use 'lethal force' at the border

DeSantis expressed support for using the U.S. military to combat drug cartels across the border.

"The president of the United States has to use all available powers as commander in chief to protect our country and the people," DeSantis said.

"When they are coming across, yes we are going to use lethal force," he continued -- a line he's used repeatedly throughout the campaign.

Activists have pushed back that his plan is inhumane and illegal.

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).
