One of the top priorities of the Republican-led Congress and the Trump administration is repealing and replacing the Affordable Care Act (ACA), President Barack Obama's landmark health care law.
Even supporters of the ACA want to repair its flaws, such as a lack of competition in some state insurance marketplaces. But because the ACA has also made major improvements to the health sector, it will be very difficult to craft a replacement that doesn't disrupt insurance markets or increase the ranks of the uninsured.
