It’s looking like the President can ask the The Secretary of Education to do it. I just found the text and controll-f’ed section 432 that says the secretary may :

“enforce, pay, compromise, waive, or release any right, title, claim, lien, or demand, however acquired, including any equity or any right of redemption.”

I don’t suppose I could talk my way out of that one, but perhaps those against such policy with friends on the judicial bench would fare better than I.
