The Trump administration's latest blow to Obamacare is rattling health insurers as they draw up rate proposals, sparking new worries about huge premium increases just before midterm elections. The administration's decision to freeze a $10 billion program designed to protect insurers from big losses in Obamacare injected more volatility into insurance marketplaces, which President Trump's health department has sought to undermine. And the move swiftly drew new warnings from insurers that higher premium increases could soon follow when enrollment reopens in November. (Paul Demko, Politico)
