The Biden administration’s Justice Department on Wednesday switched positions in a major case at the U.S. Supreme Court, informing the justices that the government would not support the Trump-era argument that the Affordable Care Act was unconstitutional and should be struck down.

In a letter to the clerk of the court, Deputy Solicitor General Edwin Kneedler wrote: “Following the change in administration, the Department of Justice has reconsidered the government’s position in these cases.”
