Several groups of professors in the United States are suing the Trump administration over its policy of arresting, detaining, cancelling visas, and deporting students who participate in pro-Palestinian advocacy.

The crackdown on free speech is creating a chilling effect across US academia, argues Jamil Jaffer, executive director of the Knight First Amendment Institute at Columbia University, which is one of the organisations that brought the lawsuit.

Jaffer tells host Steve Clemons that the issue is much wider than the rights of non-citizens in the country. The government’s actions have the effect of “stifling a political viewpoint that the government doesn’t like”.
