Former U.N. ambassador Nikki Haley called on Republicans to move on from "stale ideas" and "faded names," a veiled swipe at her former boss Donald Trump, as she made her first stop on Wednesday in a campaign for the 2024 presidential nomination.

The former South Carolina governor is just the second Republican to seek the party's backing to challenge Democrat and current U.S. President Joe Biden, who is expected to seek re-election next year.

Haley, the daughter of Indian immigrants, hit on a long list of Republican concerns in her speech in Charleston, including border security, spending bills authorized by Democrats in Congress and the recent incursion into U.S. airspace of what U.S. security officials say was a Chinese spy balloon.
