Supreme Court rulings and political opposition threaten Biden's student debt plan.

The fate of President Biden's plan to discharge billions of dollars of student loan debt hangs in the balance as the conservative-majority Supreme Court is set to rule on two cases challenging the proposal. The court's decision could affect up to 43 million people eligible for up to $20,000 in debt relief, with the total cost estimated at more than $400 billion. The court is also set to rule on a host of other big issues, including another education-related dispute that could end the consideration of race in college admissions.
