In the midst of the coronavirus pandemic, the Trump administration on Thursday urged the Supreme Court to overturn the Affordable Care Act. The administration’s latest high court filing came the same day the government reported that close to half a million people who lost their health insurance amid the economic shutdown to slow the spread of COVID-19 have gotten coverage through HealthCare.gov. The administration’s legal brief makes no mention of the virus. Some 20 million Americans could lose their health coverage and protections for people with preexisting health conditions also would be put at risk if the court agrees with the administration in a case that won’t be heard before the fall.
