Trump threatens to shift billion in Harvard grants to US trade schools

WASHINGTON, May 26 (Reuters) – U.S. President Donald Trump said on Monday he is considering taking $3 billion of previously awarded grant money for scientific and engineering research away from Harvard University and giving it to trade schools. His comments on his social media platform Truth Social come less than a week after his administration sought to block the Ivy League school from enrolling foreign students as part of Trump’s extraordinary effort to seize some government control of U.S. academia. Trump, a Republican, has frozen some $3 billion in federal grants to Harvard in recent weeks, complaining that it has
