From The Arc of the United States:

Harmful Health Care Bill is Coming Back – Act Now!
Thank you for calling, emailing, visiting, and sharing your stories with your Members of Congress and about the importance of the Affordable Care Act (ACA) and Medicaid. Because of your hard work, the House of Representatives has once pulled back from a vote on the American Health Care Act. Medicaid and the ACA, which provide essential supports and services, were protected – but the bill is now back on the table and potentially moving quickly.

We must remain vigilant. Stay engaged:
