Trump administration wants all of Affordable Care Act struck down

President Obama signing the Affordable Care Act, also known as Obamacare.

The Trump administration has told a federal appeals court it wants the entire Affordable Care Act, known as "Obamacare," struck down.

In a filing Monday with the New Orleans court, the administration said the entire law should be struck as unconstitutional. It's rare for the Justice Department to decline to defend a federal law, but President Donald Trump has long unsuccessfully sought to repeal the 2010 health care statute.

In June, Trump administration lawyers stopped defending key parts of the law, including its guaranteed access to health insurance for people with pre-existing medical conditions. But the administration had said that the rest of the law could stay.

Millions of people benefit from the ACA's taxpayer-subsidized private insurance plans, but enrollment is declining.

The Justice Department is expected to elaborate on its position in a brief to the appeals court. In a letter, it said the appeals court should affirm a December decision by U.S. District Judge Reed O'Connor in Fort Worth, Texas. O'Connor ruled that Congress' elimination of penalties for not buying health insurance rendered the law unconstitutional.

The ruling rests on a legal analysis that the coverage requirement and its fines remain central to the law. O'Connor noted that the Supreme Court upheld the law in 2012 because the mandate was enforced through fines that passed constitutional muster, since they were levied as taxes.

With the fines gone, the coverage requirement can no longer be considered constitutional, he reasoned, and the entire health law is defective because it can't be separated from the coverage requirement.

The health law, signed by then-President Barack Obama, remains in place while the lawsuit continues. House Democrats, meanwhile, are unveiling broad legislation to shore up the Affordable Care Act.
