As Medicaid coverage shrinks, millions of Americans are losing access to care. An estimated 10 million people could lose insurance over the next three years. To meet the growing need, the nonprofit Remote Area Medical runs free pop-up clinics across the country, serving patients who can’t afford care. Patients sometimes wait for days and sleep in their cars for a chance to receive life-changing care they desperately need. Scott Pelley reports, Sunday. #medicalcare #uninsured #nonprofit
