Crowd at Black church cheers as Biden calls Trump a “loser” and chants “four more years” in a speech that attacks the former president for claiming the Civil War is “negotiable” and Nikki Haley says slavery is not a cause used to be

President Joe Biden on Monday used one sentence to slam both former President Donald Trump and his rival Nikki Haley over comments they recently made about the Civil War.

Biden traveled to Charleston, where he appeared at the historic Mother Emanuel AME Church, as he looks to shore up his 2024 support among Black voters.

While he was interrupted at one point by pro-Palestinian protesters shouting “ceasefire now,” he was also rewarded with cheers when he called Trump a “loser” and chants of “four more years.”

“So let me be clear for those who don't seem to know: slavery was the cause of the Civil War,” Biden said, earning applause. “There was no negotiation about that.”

Last month, Haley, the former governor of South Carolina, intervened when she failed to bring up slavery when a visitor to New Hamsphire City Hall asked her what caused the Civil War.

“Well, don't come with an easy question or anything,” Haley told the congregation attendee.

“I mean, I think the cause of the Civil War was really how the government would function, the freedoms and what people could and couldn't do,” Haley then responded.

Haley, the former governor of South Carolina, asked the man for his thoughts on the start of the Civil War and he then noted that in 2023 he found it “amazing” that she wouldn't mention the word “slavery.”

“What do you want me to say about slavery?” Haley then said.

On Saturday, Trump came in and told supporters at a campaign stop in Newton, Iowa, that he believed the Civil War was “something that could be negotiated.”

“The Civil War was so fascinating, so terrible,” Trump said. 'I find it so attractive to see it. So many mistakes have been made. You see, there was something that could be negotiated. Frankly, I think you could have negotiated that.”

He added that President Abraham Lincoln “if he were to negotiate it, you probably wouldn't even know who Abraham Lincoln was.”

On Saturday, former President Donald Trump told his supporters in Newton, Iowa that the Civil War could have been “negotiable.”

“He would have been president … but he wouldn't have been 'the' Abraham Lincoln, but that would have been fine,” Trump added.

Trump spent a few moments noting the horrific death toll – estimated at 620,000.

'So many people have died. That was the disaster. If you were hit in the leg by a bullet, you would actually die or lose your leg, that's why you had so many people – no legs, no arms… because the infection, gangrene – it was just like that, kind of a terrible time.'

He added that it was a “cruel, cruel war” and a “tough war for our country.”

So far, of the three Republican candidates, only Florida Governor Ron DeSantis has remained unscathed in the Civil War controversy.

“I don't even know how to judge — I don't even know what he's talking about,” DeSantis told ABC News on Sunday, responding to Trump's comments during a campaign stop in Iowa. “Lincoln did what he had to do, he finally ushered in the abolition of slavery and he saved the union.”
