What does Trump's executive order on antisemitism entail and why is it controversial?

Trump's executive order titled 'Additional Measures to Combat Antisemitism' establishes a policy to prosecute, remove, or hold accountable perpetrators of unlawful antisemitic harassment and violence. While the Anti-Defamation League has applauded it as a step against rising antisemitism, many are concerned about its implementation. The controversy stems from the heated debate over what constitutes antisemitism, with critics viewing it as potentially targeting pro-Palestinian activists, especially foreign students who could have their visas canceled. Legal experts note that while current law protects lawful beliefs and statements, the order creates uncertainty by suggesting that those associated with 'terrorist groups' could lose their visas, raising free speech concerns.
