President Donald Trump is moving to block nearly all foreign students from entering the country to attend Harvard University, his latest attempt to choke the Ivy League school from an international pipeline that accounts for a quarter of the student body.

The Trump administration has stripped billions of dollars in federal funding from Harvard, alleging that the university is not doing enough to address antisemitism on campus. Mr. Trump said Monday he's considering rerouting $3 billion in Harvard grants to U.S. trade schools across the country.
