Use of the Annual Appropriations Process to Block Implementation of the Affordable Care Act (FY2011-FY2016) [January 5, 2016] [open pdf - 701KB]
"Congress remains deeply divided over implementation of the Affordable Care Act (ACA), which President Obama signed into law in March 2010. Since the ACA's enactment, lawmakers opposed to specific provisions in the ACA or the entire law have repeatedly debated its implementation and considered bills to repeal, defund, delay, or otherwise amend the law. To date, most of this legislative activity has taken place in the House, which reverted to Republican control in 2011. Over the past five years, the Republican-led House has passed numerous ACA-related bills, including legislation that would repeal the entire law. There has been far less debate in the Senate, which remained under Democratic control through 2014. Most of the ACA legislation passed by the House during that period was not taken up by the Senate. However, a few bills to amend specific elements of the ACA that attracted sufficiently broad and bipartisan support were approved by both the House and the Senate and signed into law. Now that Republicans control both chambers of Congress, opponents of the ACA see new opportunities to pass and send to the President legislation that would change the law. In addition to these attempts to repeal or amend the ACA through authorizing legislation, some lawmakers have used the annual appropriations process in an effort to eliminate funding for the ACA's implementation and address other concerns they have with the law. […] This report summarizes the ACA-related language added to annual appropriations legislation by congressional appropriators since the ACA was signed into law."
