As Trump attacks the Affordable Care Act, we look at the growing case for Medicare for all. More than 100 Democratic lawmakers co-sponsored a House bill last month to dramatically revamp healthcare in the United States by creating a Medicare-for-all system funded by the federal government. The bill would expand Medicare to include dental, vision and long-term care, while making the federally run health program available to all Americans. It would also eliminate health insurance premiums, copayments and deductibles. We speak with Dr. Adam Gaffney, president of Physicians for a National Health Program, which has endorsed the measure.
