Typical Clinton campaign lie
This sounds like a tyical Clinton campaign lie. You must work with the campaign.
The company is not named. No one knows exactly what a Walmart brand company is.
Nothing specific is offered about the alleged overcharges. It is well know that all hospitals, even those run by some churches, do not extend the discounts negotiated with HMOs to uninsured patients. I do not like the practice but it is almost universal.
