Florida Gov. Ron DeSantis, former U.S. Ambassador to the U.N. Nikki Haley, former New Jersey Gov. Chris Christie and tech entrepreneur Vivek Ramaswamy are squaring off in Tuscaloosa.

Entrepreneur Vivek Ramaswamy generated a round of early boos when he accused former South Carolina governor Nikki Haley of being a “fascist” for her views on social media. “We’re marching toward fascism under Biden,” Mr Ramaswamy said. “The only person more fascist than the Biden regime now is Nikki Haley.”
