A fresh lawsuit revives an old challenge for President Joe Biden — delivering on his 2020 campaign pledge to forgive student loans.

Biden announced in 2022 that he’d “cancel” $10,000 of federal student debt per borrower, only to see his plan ruled illegal by the Supreme Court. He has since announced another $144 billion in student debt writeoffs and created a program to lower future payments, but he was slapped with a new lawsuit by a coalition of Republican-led states on Thursday.
