The SAVE program is a replacement for REPAYE

It has some relatively modest changes from REPAYE. REPAYE, incidentally, began under the Trump administration (Edit: actually it was announced prior to Trump but implemented by him, apologies). But of course income-based payment, deferral, and forgiveness has a long, bipartisan history.

One of the changes is to accelerate the forgiveness period from 20 years to 10 for loans under $12,000 (it gradually increases up to 20 now, based on loan size). This change was scheduled to take effect this coming July but was moved up by six months.

It’s this action that you apparently find impeachable.
