Students have returned to college campuses this fall, but undergrads at New York University’s Stern School of Business say one special classmate is nowhere to be found: First Son Barron Trump.

“Missing” media reports are exploring the whereabouts of the youngest son of President Donald Trump. The 19-year-old, who was supposed to start his sophomore year, has gone off the radar in recent days, prompting public concern for his well-being.

Campus security confirmed to TOI that Barron has not been present on the main campus in Greenwich Village. However, the expansive school reaches beyond just one leafy enclave of the city.

With campuses in Downtown Brooklyn, Shanghai, and Dubai, the Stern School of Business offers its students the chance to study in far-flung places around the world, hobnobbing with rich and powerful businessmen all too eager to impart their life lessons on burgeoning young minds.

It’s uncommon for sophomores to study abroad, but Barron’s unique circumstances and security needs may place him in a position to qualify for an advanced trip.

Officials from both NYU and the Trump family declined to give specifics but confirmed that Barron is “doing a semester at another NYU campus.”
