Despite putting a temporary hold Monday on a decision approving a U.S. House Committee subpoena for President Trump’s financial records, the U.S. Supreme Court soon will face a more critical question: whether to hear and decide the president’s separation-of-powers challenge in the current term.

Chief Justice John Roberts Jr. on Monday issued the order blocking the appellate court’s decision to leave untouched an October panel decision that said Trump’s accounting firm, Mazars USA, must respond to the House subpoena for eight years of financial information.
