Rep. Alexandria Ocasio-Cortez (D-N.Y.) has fired back at conservative critics who accused her of adopting a faux “Southern drawl” for her speech at Rev. Al Sharpton’s National Action Network convention in New York on Friday. Ocasio-Cortez tweeted that “folks talking about my voice can step right off.” “Any kid who grew up in a distinct linguistic culture & had to learn to navigate class enviros at school/work knows what’s up,” she added. “My Spanish is the same way.”
