Midterm results may limit Trump's foreign policy, but Democrats lack the numbers to override his vetoes

Summary

US President Donald Trump's foreign policy agenda faces new constraints after Democrats gained ground in the midterm elections, according to Al Jazeera and The Guardian, reporting on 4 and 5 November 2026. Democrats can block parts of Trump's legislative agenda and launch investigations, but they do not have the numbers to override his veto. The Guardian reports that Trump's war in Iran and international tariffs played a key role in the inflationary pressures that drove many Americans to vote against his party, which it describes as a 'generational wipeout' for Republicans. It expects Democrats, who will control Congress, to threaten investigations of some of Trump's top envoys and Pentagon contractors, to fight over budgets linked to the Iran war, and to scrutinise US relationships with allies such as Israel. The Guardian adds that the president still has veto power, which he can use to dictate policy on tariffs, the war in Iran or aid for Ukraine. Al Jazeera asks whether Democrats will therefore struggle to rein in his policies, including tariffs and the Iran war.
