Haley made her announcement in a 3½-minute video released online, in which she declares, “It’s time for a new generation of leadership.” The video emphasizes Haley’s gender and her family’s immigrant roots.

A veteran of the Trump administration, Haley begins as an underdog in the GOP race. If successful, she would become the first woman and first Asian American to lead the Republican ticket. She previously made history as the country’s first female Asian American governor and the first Indian American to serve in the Cabinet.

Haley has shifted her posture toward Trump over the years. She criticized him when he first ran in 2016, before joining his administration the next year and later vowing not to run against him in 2024. In recent months, she has disavowed the pledge as she moved toward a planned announcement speech here in Charleston on Wednesday.
