Conservative groups are flooding the Supreme Court with calls to block Biden's student-loan forgiveness, arguing that borrowers are 'contractually bound to repay their loans'

• Nine conservative groups this week filed amicus briefs to the Supreme Court opposing Biden's student-debt relief.
• One of them argued that all borrowers have an obligation to pay back the loans they borrowed.
• It comes after advocates and scholars filed over a dozen briefs supporting Biden's plan.

In less than a month, the nation's highest court will hear arguments on the legality of President Joe Biden's plan to cancel student debt. 

Conservative groups are making sure the court hears their opinion: that student-loan forgiveness is illegal and should be blocked.
