WASHINGTON (AP) — President Joe Biden’s latest plan for student loan cancellation is moving forward as a proposed regulation, offering him a fresh chance to deliver on a campaign promise and energize young voters ahead of the November election.

The Education Department on Tuesday filed paperwork for a new regulation that would deliver the cancellation that Biden announced last week. It still has to go through a 30-day public comment period and another review before it can be finalized.

It’s a more targeted proposal than the one the U.S. Supreme Court struck down last year. The new plan uses a different legal basis and seeks to cancel or reduce loans for more than 25 million Americans.

Conservative opponents, who see it as an unfair burden for taxpayers who didn’t attend college, have threatened to challenge it in court.

The Democratic president highlighted the the plan during a trip to Wisconsin last week, saying it would provide “life-changing” relief. He laid out five categories of people who would be eligible for help.
