If the Republican tax cuts bill becomes law, it will immediately trigger a $25 billion cut in Medicare.

And as Sarah Kliff reminds us, what happened then was that cancer patients were turned away from clinics, because the clinics couldn’t afford the expensive chemotherapy drugs they were administering without Medicare offsetting the costs.
