A US federal court has overturned billions in funding cuts by President Donald Trump's administration to Harvard University. Judge Allison Burroughs ruled the government violated the Ivy League college's free speech rights when it revoked around $2bn (1.5bn) in research funding. The ruling is a major legal victory for Harvard, but is likely to be appealed. The Trump administration accused the college of antisemitism, "radical left" ideologies and racial bias when it froze the funding in April.
