For decades, the Justice Department has operated with a widely shared understanding: that prosecutors should follow the evidence, not the president.

That understanding was never written into law; it was shaped by norms. And now those norms are being tested.

This season on UnCommon Law, we hear from former attorneys general, constitutional law scholars, and federal prosecutors who have watched from inside as changes have reshaped the Justice Department.

But supporters of the president say he has the power to direct the Justice Department — perhaps even the duty to do so.

What happens when a president takes an active role in directing law enforcement priorities? What happens to a Department of Justice built on norms, when those norms are challenged?

This is Justice Transformed. A new season of UnCommon Law, from Bloomberg Industry Group.
