What’s in a name? Everything for Rep. Alexandria Ocasio-Cortez.

The New York Democrat blasted Fox News host Laura Ingraham and her guest for mocking how she pronounced her name and saying she does so because it’s a “Latina thing.”

“If by ‘the Latina thing,’ she means I actually do the work instead of just talk about it, then yeah, I’m doing ‘the Latina thing,’” she wrote on her Twitter page late Wednesday. “Unless of course she‘s talking about being multilingual, which we know isn’t a ‘Latina thing.’ It’s a ‘21st century’ thing.”

Ocasio-Cortez also said that Fox News’ hosts incorrectly pronounce her name as “Cortez,” because that sounds “more ‘stereotypically’ Hispanic + probably incites more ‘anxiety’ for them.”

“Pro Tip: My last name is not ‘Cortez,’ just as theirs isn’t ‘Ingra’ or ‘Carl’ or ‘Hann,'” she said, referring to Tucker Carlson and Sean Hannity.

Ingraham, on her Fox News show “The Ingraham Angle” on Tuesday, asked guest Joe diGenova if he had noticed how when Ocasio-Cortez pronounces her name “does she take on that Obama, Obama put on accents?”

“She does the Latina thing where she does her, you know, ‘Anastasio Ocasio-Cortez,'” said diGenova, a conservative lawyer, exaggerating the pronunciation.

Ingraham went on to call Ocasio-Cortez the “It Girl, and I mean girl in a very mature way.”

Ocasio-Cortez continued to school the two on the correct use of her name.

“My last name is Ocasio-Cortez. Full stop. That’s my name. No, you can’t say ‘Cortez.’ I’ve never used that in my life,” she said. “‘Cortez’ is referring to someone else. Even if they‘re trying to be rude + wrong, my dad’s last name was Ocasio anyway. (His name was hyphenated too, though.)”

She continued: “For the curious, in Latinx culture children take both their parents‘ names.

“It’s not a ‘progressive, new thing.’ It’s just how some names work. PR hyphenates, others mark differently. Your last name = the families that came together to make you,” she tweeted. “AOC is also fine though :)”
