What the midterm elections mean for Trump's agenda

Democrats have won control of both chambers of Congress in Tuesday's midterm elections, positioning themselves to challenge President Donald Trump's administration, though their actual power to enact change faces significant constitutional limits. On trade, Democrats cannot easily reverse Trump's tariffs since he imposed them by executive order and holds veto power over any repeal legislation, requiring a two-thirds majority to override. On the Iran war, Democrats plan to use their budgetary and investigative powers to restrict military spending and probe Defense Secretary Pete Hegseth, though new members take office only in January. On immigration, Democrats intend to scrutinize funding for the Department of Homeland Security and ICE, potentially attaching conditions to budgets and launching investigations into officials. However, experts note Trump may respond unpredictably, and Vice President J.D. Vance has publicly blamed the Iran war for Republican losses.
