Donald Trump used his social media platform Friday to mock Nikki Haley ‘s birth name, the latest example of the former president keying on race and ethnicity to attack people of color, especially his political rivals.

In a post on his Truth Social account, Trump repeatedly referred to Haley, the daughter of immigrants from India, as “Nimbra.” Haley, the former South Carolina governor, was born in Bamberg, South Carolina, as Nimarata Nikki Randhawa. She has always gone by her middle name, “Nikki.” She took the surname “Haley” upon her marriage in 1996.

Trump, himself the son, grandson and twice the husband of immigrants, called Haley “Nimbra” three times in the post and said she “doesn’t have what it takes.”
