Chief Justice John Roberts and Justice Brett Kavanaugh suggested Tuesday that it wasn't the Supreme Court's role to invalidate the entire sprawling, 900-page Affordable Care Act, even if one or more provisions are deemed unconstitutional, signaling the key parts of Obamacare will survive the latest court challenge.

As the pandemic rages, President Donald Trump lashes out at election returns and President-elect Joe Biden prepares for a new administration, the Supreme Court heard oral arguments to discuss whether to invalidate the linchpin of the nation's health care system.

The Trump administration and several Republican-led states are asking the court to strike down the law, 10 years after it was passed, potentially impacting millions of Americans. Should Roberts and Kavanaugh, at the very least, side with the court's three liberals, the law would remain intact.
