President Donald Trump has been waging a campaign to pressure elite US colleges to make a wide range of policy changes, in what his administration has framed as an initiative to fight campus antisemitism and enforce civil rights protections.

The Trump administration's decision to block Harvard University from enrolling foreigners has caused shock and confusion among students. Harvard called the government's move "unlawful" and said it will fight the ban.
