Six Republican-led states on Thursday filed a challenge to the Biden administration’s student loan cancellation program in federal court in Missouri on Thursday.

In the lawsuit, Nebraska, Arkansas, Iowa, Kansas, Missouri, and South Carolina asked the court for an immediate temporary restraining order pausing the program.

Prompt relief is being sought because the Biden administration has indicated it will start canceling loan balances as early as next week, Nebraska Attorney General Doug Peterson said in a statement.

The lawsuit comes two days after conservative group Pacific Legal Foundation filed a federal lawsuit with the intent of stopping President Joe Biden’s student loan cancellation plan.
