Just days after President Joe Biden announced student debt cancellation, his administration is under fire for continuing to try to deny bankruptcy protections to the most beleaguered debtors.

Earlier this year, the Lever broke the news that contrary to Biden’s campaign pledge, his administration officials have been fighting student debtors in bankruptcy court and appealing rulings that erase or reduce borrowers’ student debts. After a public outcry, Biden’s Justice Department said it would review its policy on such cases, but hasn’t yet announced any changes.

Now, Senator Elizabeth Warren (D-MA) is demanding answers about the Justice Department’s legal posture.
