On Capitol Hill, Vermont independent Senator Bernie Sanders introduced a bill Wednesday that would provide universal healthcare by expanding Medicare to include every American. Sanders introduced the bill flanked by doctors, nurses and some of the bill’s 15 Democratic co-sponsors.

Sen. Bernie Sanders: “Today, we begin the debate, vital to the future of our economy, as to why it is that in the United States we spend almost twice as much per capita on healthcare as any other nation on Earth, and yet we have 28 million people without any health insurance and even more who are underinsured, with high deductibles and copayments.”

Sanders unveiled his Medicare-for-all bill as Senate Republicans launched another attempt to repeal the Affordable Care Act—after the party’s two previous efforts ended in humiliating defeat.
