The spending fight is one aspect of a broader discussion about whether Congress has ceded too much power to the president, either by passing laws that expand his authority or empowering him through their own inaction.

The Constitution assigns to Congress the power to levy tariffs, and some lawmakers within both parties say they have gone too far in delegating that authority to the president. Separately, a handful of lawmakers within each party want to scale back laws that give the president enhanced powers during emergencies, which Trump has cited in some of his actions regarding energy production, tariffs and immigration.

Other separation-of-powers battles could be on the horizon, including one over the authority of federal courts as they consider the legality of Trump’s executive actions.
