The Supreme Court Tuesday heard oral arguments to discuss whether to invalidate the linchpin of the nation's health care system.
Chief Justice John Roberts and Justice Brett Kavanaugh suggested 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.
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. It will be months before the justices have a ruling.
