The document discusses the Patient Protection and Affordable Care Act (Obamacare), signed into law in 2010. It overviews the national focus on healthcare reform to lower costs and increase access.

The Supreme Court affirmed the constitutionality of the law in 2011, though it remains an ongoing source of debate.
