Tariffs to Iran war: Can Democrats reverse Trump policy with midterms win?

Democrats won control of both chambers of Congress in the US midterm elections, giving them greater scope to investigate and challenge President Donald Trump’s policies. They may also block legislation, but the result does not automatically reverse decisions Trump can make without congressional approval, including military action and some trade measures.

The article focuses on the war with Iran and tariffs. Trump began the war with Israel in February without authorisation; Congress could seek to limit funding when the current funding bill expires on 11 December, though experts say this could be difficult and the War Powers Resolution is unlikely to stop him. Democrats lack the two-thirds majorities needed to override a presidential veto, while Trump’s administration has pursued tariff workarounds after the Supreme Court struck down his earlier measures.
