The Biden administration said it plans to make it easier for lower-income student-loan borrowers to get debt forgiveness through an existing program that has enrolled millions of people, but provided few with relief.

The move, announced by the Education Department on Tuesday, is part of a politically sensitive debate on the forgiveness of student-loan debt and attempts to more broadly overhaul how the student-loan repayment system works. President Biden earlier this month extended to Aug. 31 a pandemic-related pause on payments of federal student loans and faces pressure from progressive members of his own party to forgive debt on a larger scale.
