(L/R) US Senator-elect Sherrod Brown, Democrat from Ohio, and Senator-elect Chris Pappas, Democrat from New Hampshire, walk through the US Capitol as they arrive for new member orientation meetings for the 120th Congress, in Washington, DC, on November 9, 2026. The US House of Representatives and Senate returned to session on Monday, with Republicans in control of the "lame duck" Congress until the end of 2026. Democrats will control the upcoming 120th Congress following their massive gains in the midterm elections in a nationwide rejection of President Donald Trump, set to put the brakes on the final two years of his presidency. The Democratic landslide will give the opposition power to block legislation, launch broad investigations into Trump's administration and thwart his judicial and senior government appointments.
