Democrats won control of both the House of Representatives and the Senate in Tuesday’s midterm elections, taking the majority in both chambers away from Republicans and changing the balance of power in Washington for the final two years of President Donald Trump’s term, according to NBC News projections.

The results give Democrats control of Congress for the first time since the 2006 midterm elections. The party will now lead both chambers, giving it greater authority over which legislation receives consideration and how Congress conducts its business.In the House, Democratic

Minority Leader Hakeem Jeffries of New York is expected to become speaker, succeeding Republican Mike Johnson. The speaker oversees the chamber’s proceedings and plays a central role in determining which legislation moves forward. A formal vote is scheduled for Jan. 3, when the new Congress begins.

The change in Senate control will give Democrats leadership over the chamber’s legislative process and greater influence over presidential appointments. The party will also have the ability to decide whether Trump’s nominees for federal positions, including judgeships, advance through the confirmation process.

Control of both chambers will also give Democrats expanded authority to oversee the executive branch. Congressional committees can hold hearings, request documents and investigate federal agencies and administration officials. Democratic lawmakers have indicated that they intend to use those powers to examine decisions made by the Trump administration.

However, Democrats will not have control of the presidency, as Trump will remain in office and retain his veto power, meaning legislation opposed by the administration could face additional obstacles. The change in congressional leadership is therefore likely to create a different relationship between the White House and Congress. The new Congress will take office Jan. 3, 2027.
