Rep. Alexandria Ocasio-Cortez loves to call herself a “Bronx girl.” But one New York lawmaker is calling her bluff — with photographic proof.

Republican State Assemblyman Matt Slater, who represents the region AOC actually grew up in, dropped the hammer on the far-left congresswoman this week, exposing what he called a “charade” surrounding her upbringing.

“If you’re a BX girl then why are you in my Yorktown yearbook? Give it up already,” Slater posted to X, attaching a photo of Ocasio-Cortez from their days at Yorktown High School, an affluent public school in Westchester County — more than an hour north of the Bronx.

Slater, who was a senior when AOC was a freshman, said he finally had enough after watching her post yet another tough-girl boast on social media while attacking President Donald Trump over his precision strikes on Iranian nuclear targets.

“When I saw the tweet making her out to be this tough Bronx girl, I’d just had enough,” Slater told Fox News Digital. “I literally just reached behind me and grabbed my yearbook, clicked the photos and said: ‘Listen, enough is enough.’”

“You’re from Yorktown,” he added. “Let’s end this charade and come clean.”

The internet feud began when Ocasio-Cortez demanded Trump’s impeachment over his authorization of military action — a position that echoed the radical anti-war fringe of her party.

President Trump responded forcefully on Truth Social, blasting Ocasio-Cortez as “stupid” and “one of the ‘dumbest’ people in Congress,” and questioning her qualifications for office.

“When we examine her Test Scores, we will find out that she is NOT qualified for office,” Trump wrote, adding she’s “far more qualified than Crockett, who is a seriously Low IQ individual, or Ilhan Omar, who does nothing but complain about our Country.”

Ocasio-Cortez fired back with one of her signature Bronx-girl one-liners:

“Also, I’m a Bronx girl. You should know that we can eat Queens boys for breakfast. Respectfully,” she wrote, referring to Trump’s Queens upbringing.

But Slater wasn’t having it. He pointed out that Ocasio-Cortez didn’t grow up in the Bronx — she grew up in Yorktown Heights, where her family moved when she was five years old to get access to better schools.

“That fact that she continues to go on this charade, I think disrespects this town,” Slater said. “People just want real leaders, and not manufactured, fake folks who feel like they have to hide their past or create this false narrative to score points or votes and get attention.”

“I went to college in New Hampshire. I don’t say I’m from New Hampshire,” he quipped.

Ocasio-Cortez has long claimed her Bronx upbringing to score political points with working-class voters. While she did spend her early childhood in Parkchester, she left the Bronx for the suburbs before starting school.

In a 2018 tweet, she described Yorktown Heights as “nice” and said her mother “scrubbed toilets” so she could grow up there — a comment critics have called a deliberate effort to obscure her suburban background.

Slater called out the inconsistency:

“Clearly, hiding or distorting her roots was done for a very specific reason and obviously that reason was to help her get elected,” he said. “If you’re not going to be honest about it, then we’re going to be honest for you.”

AOC has built her brand on identity politics and performative outrage. But according to her own yearbook, the “Bronx girl” persona may be just that — a persona.
