In brief
With a sweeping Democratic victory, the new Congress can pressure President Trump on foreign policy through war‑powers resolutions, tariff legislation, and oversight hearings. Iranian officials welcomed the results as a rebuke of Trump’s hard‑line approach, signaling a potential shift in U.S.–Iran relations. The depth and speed of policy changes will depend on congressional vetoes and political divisions.
The United States midterm elections on Nov. 5 handed the Democrats a sweeping victory, potentially giving Congress new leverage over President Donald Trump’s foreign policy stances on Iran, trade, and Ukraine.
According to Xinhua, the incoming Democratic-controlled Congress may step up scrutiny of Trump’s military actions against Iran, roll back some of his tariffs, and push for stronger support for Ukraine, while Trump’s veto power and a lack of a supermajority could limit the speed and depth of changes.
The Washington Post, citing the Associated Press, reported that Iranian officials welcomed the results, describing them as a “clear rebuke to Trump’s hard‑line approach.” The diplomatic comments came amid reports that Iran’s leadership views the U.S. political transition as an opportunity to re‑examine its relationship with Washington.
Schumer said Wednesday that the incoming majority could use Congress’s control over federal spending to pressure Trump to end the war in Iran. The American people don’t know what the heck we’re fighting for in Iran, Schumer told journalists, noting that the “power of the purse” is one way of deterring a president who goes to war without consent.

Trump himself acknowledged that the war was partly responsible for the Republican defeat, although he refused to regret launching it. Democratic lawmakers have already voted on seven war‑powers resolutions concerning Iran, with two passing, and are poised to hold further votes, according to a source cited by Xinhua.
On the trade front, Democrats are expected to pursue tariff rollback, while Ukraine support may see intensified aid and legislative backing as the new majority seeks to counter Russian influence.
Overall, the extent of policy shifts will hinge on how swiftly the new Congress can translate its electoral gains into concrete legislative action amid ongoing political polarization.
