Just before Thanksgiving, the Trump administration was gearing up to intervene, potentially resolving the crux of the issue before the end-of-year holidays. Multiple news outlets reported that Trump planned to propose prolonging the subsidies for two year, but the president pumped the breaks amid opposition from congressional Republicans.
