US President Joe Biden made a sweeping promise—with a stroke of his pen, he was going to wipe out billions of dollars in student loan debt for graduates in the US. He made good on that pledge by signing an executive order that gave some relief to some borrowers. But now he's scaling it back, and depending on how he handles challenges to its legality, he may have to walk it back entirely. In this episode of America Uncovered, we look at the legal basis Biden used for his executive order, what challengers to his order are saying about its legality, and how the Biden administration is changing who is now eligible to receive relief.
