South Carolina Gov. Nikki Haley, a rising Republican star and daughter of Indian immigrants, has accepted President-elect Donald Trump’s offer to serve as U.S. ambassador to the United Nations in the coming administration, according to a person familiar with the selection process.

The move, which will be announced Wednesday morning and was first reported by the Post and Courier, comes as Trump advisers are seeking to diversify his ranks and marks his first female appointment to a cabinet-level post.

The person spoke on the condition of anonymity to discuss a decision that has not yet been announced by Trump’s transition team.
