The high-stakes congressional elections featured all 435 seats in the House of Representatives, where Republicans defended a narrow majority, alongside 35 Senate races and key state-level contests. Democrats aimed to flip both chambers to establish a legislative check on the executive branch for the final two years of President Trump's term. Notable early outcomes included James Talarico defeating Trump loyalist Ken Paxton, and Sherrod Brown defeating incumbent John Husted.

As election results unfolded, President Trump monitored coverage from the White House while officials cautioned that determining the final outcomes in close races across the country could take days or weeks.
