Nikki Haley has accepted Donald Trump's offer to be US Ambassador to the United Nations:
Personally, I don't see what great skills she brings to the UN ambassador role, since she has no foreign policy experience. On the one hand, since she's Indian and a woman, it shows he's supporting "diversity", etc. On the other hand, she did quickly participate in attacking Trump during the Republican Primary, at the behest of the establishment - so perhaps Trump is moving her to a position where she cannot be readily co-opted by the treacherous establishment to be the face of a future rebellion they might mount against him.
Tulsi Gabbard would have been a better choice, in terms of her knowledge and experience.
