US Immigration and Customs Enforcement officers detained a Turkish doctoral student at Tufts University without charges or explanation, raising concerns of a new version of McCarthyism in the US. The targeting of academics and students, such as Rumeysa Ozturk and Mahmoud Khalil, is seen as a crackdown on pro-Palestinian activism. The Trump administration has warned universities of possible action over alleged failure to comply with federal civil rights laws related to antisemitism. Critics argue that the state is using funds to control academia and infringe on people's rights and free speech.
