The legal mess over the ACA subsidies is only getting worse

President Trump's decision to stop paying a critical Affordable Care Act subsidy could usher in a fresh round of legal challenges, even if it helps resolve one especially sticky lawsuit between the Trump administration and House Republicans.

Why now? The White House says it's cutting off these subsidy payments because of a federal court ruling that said the payments were unconstitutional — a ruling Trump and many of his allies had largely ignored until yesterday. And by suddenly getting on board with that ruling, Trump could be inviting a new set of legal challenges designed to keep the subsidies flowing.
