NBC - South Carolina Gov. Nikki Haley has accepted Donald Trump's offer to be his ambassador to the United Nations, a source familiar with the president-elect's transition process confirmed to NBC News Wednesday.

Haley, 44, is a two-term governor. She initially backed Trump rivals Sen. Marco Rubio and then Sen. Ted Cruz during the GOP battle for a White House nominee.

She is the first woman in the state's history to hold the role.

The daughter of immigrants from India, Haley served three terms in South Carolina's State House before winning the governorship in 2010 and again in 2014.

Haley's limited foreign policy experience is likely to draw scrutiny during Senate confirmation hearings for the Cabinet-level position.

If confirmed, Haley would succeed Samantha Power, who has served as President Barack Obama's U.N. ambassador since 2013.
