How fear plays a role in politics

President Trump has signed a flurry of executive actions since taking office last month that have left many Americans uncertain and afraid.

Immigration agents are now allowed in schools and religious buildings. Federal employees may lose their jobs as billionaire Elon Musk leads a purge of government workers.

And it's not just Trump and Republicans who use fear as a political motivator. Former President Biden warned before the election that Trump was a threat to democracy.

What is the impact of this kind of fear in our political system? What role has it played historically?

Host Peter O'Dowd puts those questions to Corey Robin, professor of political science at Brooklyn College and the author of "Fear: The History of a Political Idea."
