The Affordable Care Act (ACA) of 2010 is a comprehensive healthcare reform law aimed at expanding access to health insurance, reducing healthcare costs, and improving the quality of care in the United States. The ACA significantly altered the role of Congress in healthcare policy by granting it greater authority to regulate the health insurance industry and implement a range of programs designed to enhance healthcare access, particularly for low-income individuals and families. This act also showcased the legislative processes and functions of Congress as it went through numerous revisions, negotiations, and political battles before its passage.
