Investor Kevin O’Leary seemingly bashed the Trump administration’s recent crackdown on Harvard’s international student population, calling the actions “stupid” during a Friday Fox News interview.

“Harvard’s taken a lot of heat for other stuff, but they shouldn’t be taking heat for curating amazing cohorts,” the “Shark Tank” star said while appearing on “Outnumbered.” “These kids are amazing, and we gotta keep them here.”

President Trump recently upped his attacks on the Ivy League institution, suggesting a 15 percent cap be imposed on the percentage of foreign students that Harvard University and other U.S. higher education institutions can admit. Secretary of State Marco Rubio in recent days also threatened to revoke student visas for all Chinese scholars.

“And I’ll tell you what, many of those students didn’t go anywhere. Many of those students were troublemakers caused by the radical left lunatics in this country,” Trump said of international students while speaking to reporters Wednesday from the Oval Office.

O’Leary, who teaches at Harvard as an executive fellow, shot down Trump’s claims without mentioning the president directly.

“They don’t want to leave America. They don’t hate America,” O’Leary said of the students he’s encoutered. “They want to get a passport, stay here and start a business. I think I’m one of the lone voices pointing that out.”

O’Leary continued, “Why would we want to brightest and the smartest people on earth and kick them out of the country after we spend millions teaching them? It seems stupid to me.”

Trump’s actions against Harvard have been stymied recently, as a federal judge sided with Harvard in its fight against Trump’s international students cap.
