The U.S. Department of Education is threatening sanctions against dozens of colleges, including three in Pennsylvania. The Education Department’s Office of Civil Rights sent letters to 60 institutions Monday warning them of “potential enforcement actions” if they do not “fulfill their obligations under the Civil Rights Act to protect Jewish students on campus.” Among the schools that received letters were Lehigh University, Lafayette College, and Muhlenberg College. The department said those colleges are currently under investigation for Title Six violations relating to anti-Semitic harassment and discrimination.
