President Donald Trump has repeatedly vowed to “cut waste, fraud and abuse everywhere that we can find it.” Congressional Republicans now have an opportunity to help him achieve that goal by supporting the administration’s efforts to stop hospitals from abusing a little-known federal charity care program.

Congress originally created the program, known as 340B, to help safety-net hospitals care for low-income patients. Lawmakers required drugmakers to sell heavily discounted medicines to these hospitals, with the expectation that the hospitals would pass the discounts on to patients or use the extra funds to provide more charity care.
