Biden helped pass the Affordable Care Act (Obamacare). That law guarantees affordable coverage to people who have diabetes, heart disease, cancer, or other pre-existing conditions. Trump tried to repeal that law in Congress.

He is now fighting the law in court. If the Senate confirms Trump’s Supreme Court nominee, the law that protects people with pre-existing conditions will likely be eliminated.
