Former President Donald Trump railed against Nikki Haley and Joe Biden in his final rally before the South Carolina primary.

During the hour-and-a-half remarks, Trump promoted MAGA-nomics to fix the flailing economy and slammed the multiple indictments against him while also going after Haley, who remains in the primary against him.

Speaking to thousands of fired-up South Carolinian supporters at Winthrop Coliseum in Rock Hill, Trump predicted the largest stock market crash in U.S. history if he loses to President Biden in November.

'We're not very worried about tomorrow,' Trump said of the South Carolina primary election on Saturday. 'We want to aim for November 5.'

Haley was hoping to garner support in her home state after losing Iowa, New Hampshire and Nevada, but all polls show Trump is still around 30 percentage points against the former governor of South Carolina.

In 2017, Trump tapped Haley to become his Ambassador to the United Nations, cutting short her gubernatorial term.

McMaster was voted Lieutenant Governor of South Carolina in 2014 – and when Haley vacated her position in January 2017, he took over and remains in the governor's mansion.

The South Carolina governor was present at Trump's rally on Friday and introduced the former president. McMaster was an early and avid supporter of Trump in his first bid for office, evening claiming to be the first elected politician to support Trump.
