A trio of Republican-led states called on the Supreme Court on Tuesday to halt the Biden administration’s plan to slash student debt repayments for millions of borrowers.

Republican attorneys general from Alaska, South Carolina, and Texas are challenging the Saving on a Valuable Education, or SAVE, Plan, which is aimed at lower-income borrowers to reduce their monthly payments and provide a faster route to debt forgiveness. The plan was formulated on the heels of the Supreme Court decision last year to strike down President Joe Biden’s broader student loan forgiveness program.
