Nikki Haley has blunt message for Trump, GOP as Kamala Harris gains momentum: 'Quit whining'

Former GOP presidential candidate Nikki Haley weighed in on the state of the 2024 race Tuesday as Vice President Kamala Harris gains momentum in key battleground states ahead of the November election. 

Haley told Fox News chief political anchor Bret Baier on "Special Report" Republicans and former President Trump should focus on policy and messaging instead of crowd sizes at rallies, Harris' race, or attacks on her intellect.

"You can't win on those things. The American people are smart. Treat them like they're smart," she said. "It's not about her. It's about the American people. Talk to them and let them know you need their vote."

The former South Carolina governor also encouraged Republicans to "quit whining" about Harris and "quit complaining" that she hasn’t given a formal sit-down interview since replacing President Biden at the top of the Democratic ticket.
