Trump moves to cancel student loan debt for disabled veterans

[Sapientes]

It seems that most of that debt was from a law school he attended after an Army hitch and then working as a lawyer. His injuries occurred after returning to the Army and doing time in Afghanistan.

Just to add to what you said, the school he attended (Cooley Law School) is a private, not-for-profit. I think that point has relevance as many seem to think not-for-profit somehow means "affordably priced" or "low cost". 

Here's what the article says about his service and the injuries he suffered:

"Milzarski said he led 24 soldiers on 244 combat missions and 43 engagements with the enemy. Five soldiers were killed and one seriously injured. He was awarded a Purple Heart for a ricocheted bullet that hit him in the face during combat in Afghanistan. Among his 18 awards is a Meritorious Service medal."
