The U.S. government has recently served notice on Harvard and other academic institutions: They must stop ignoring the national security implications of having Communist Chinese and pro-terrorist students on campus. 

In explaining steps being taken to restrict or terminate visas for such individuals, the State Department is rightly noting that they can put at risk public safety, proprietary information or other, vital American interests. 

Harvard is accused, among other things, of “coordinating with the Chinese Communist Party on its campus.” Many other schools, if not similarly complicit, have turned a blind-eye to the CCP’s influence and even espionage operations on theirs. 

This must stop. 

The Trump team deserves credit for taking action to that end. And its ability to do so must not be denied by federal judges as indifferent to national security as have been far too many in the academy. 

This is Frank Gaffney.
