One clear theme of Nikki Haley’s presidential announcement is unity. Over and over, her Tuesday announcement video references bringing people together.

One example she uses to emphasize that is her state’s response to hate.​

In 2015, a white supremacist killed nine Black parishioners at Mother Emmanuel AME Church in Charleston, S.C. Haley, who was governor at the time, led the state through the tragedy.
