South Carolina Gov. Nikki Haley is endorsing Mitt Romney for president.

Haley said Friday on Fox News she is throwing all of her support behind Romney in the Republican primaries. She says jobs, the economy and spending are most important and the former Massachusetts governor is the best candidate to address those issues.

Haley also says President Barack Obama seems most afraid to face Romney.

Haley is a rising star in the GOP, and her endorsement means a lot in South Carolina, the first Southern state to hold a primary election.

Romney will appear with Haley Friday afternoon in South Carolina. Haley says they will campaign together Saturday.
