HHS, the Treasury Department and the Department of Labor issued proposed rules on Friday that clamp down on short-term limited duration health plans, which offer cheap but sparse coverage that Democrats deride as “junk insurance.” The rule, which is meant to protect consumers and bolster the Obamacare exchange, would overturn a 2018 Trump-era regulation and satisfies liberal lawmakers and patient groups who have demanded the administration act since its first days in the White House.
