NEWSMAX quoted Haley: "The nominating convention is a time for Republican unity," Haley said in a statement, according to Politico. "Joe Biden is not competent to serve a second term and Kamala Harris would be a disaster for America."

Instead, she said, "We need a president who will hold our enemies to account, secure our border, cut our debt, and get our economy back on track. I encourage my delegates to support Donald Trump next week in Milwaukee."

NEWSMAX adds that Haley, who served as the U.S. ambassador to the United Nations under Trump, has not been invited to the convention, her spokesperson, Chaney Denton, said.
