Trump's Executive Levers: What He Can Do Without Congress

With a Democratic-led House and a razor-thin Senate, the legislative path for a second Trump term is effectively closed on major items. But the executive branch is not a passive instrument. The White House retains substantial unilateral authority over trade, regulation, and administrative policy — and the real action will happen there, not on Capitol Hill.

Trade is the most obvious lever. The president can invoke Section 232 of the Trade Expansion Act to impose tariffs on national-security grounds, and Section 301 for unfair trade practices, without a single vote. The International Emergency Economic Powers Act (IEEPA) offers an even broader tool, allowing sweeping tariffs or sanctions under a declared national emergency. These authorities were used aggressively in the first term and remain intact, meaning the tariff agenda can move immediately.

Deregulation is the second major front. Executive orders can direct agencies to rescind or rewrite rules, and the Congressional Review Act gives the administration a fast track to kill recently finalized regulations. More importantly, the president can install loyalists atop agencies like the EPA, FTC, and SEC, reshaping enforcement priorities without legislation. Budgetary pressure — through impoundment or simply refusing to spend — can starve programs Congress funds, a tactic that will test constitutional limits.

The Limits of Unilateral Power

None of this is frictionless. Courts remain the primary check, and aggressive executive orders on immigration, spending, or emergency tariffs will face immediate litigation. The appropriations power still belongs to Congress, so any shutdown fight becomes a test of resolve rather than authority. And political capital is finite: every unilateral move invites backlash that can erode the mandate. The realistic outcome is a fast, disruptive first year — heavy on trade and deregulation, light on structural reform — followed by a grinding legal war over the boundaries of presidential power.
