Democrats won control of both the US House of Representatives and the Senate in the November 3 midterm elections. Race calls showed that Republicans had lost their majorities in both chambers.
Democrats flipped at least seven Republican-held Senate seats, winning races in Texas, South Carolina, Kansas, Iowa, North Carolina, Ohio and Maine. In several of those states, Democrats had not won a Senate election for decades.
In the House, Democrats flipped more than two dozen districts previously held by Republicans, including some that Donald Trump had carried by double-digit margins in the 2024 presidential election.
Control of both chambers will allow Democrats to chair congressional committees and investigate the Trump administration. Legislation will still require the president's approval or enough votes in Congress to override a veto.
