Democrats have seized control of the United States Congress, winning the Senate and the House of Representatives in a nationwide rebuke of President Donald Trump that is expected to slow the final two years of his term.

In a series of historic firsts, the first Black female governor, the first openly gay male senator, the first Muslim senator, and the first female Native American governor have all won office, securing landmark victories in a vote that delivered resounding gains for the Democratic Party.

The sweeping Democratic gains in Tuesday’s election hand the opposition significant power to block legislation, open wide-ranging investigations into Trump’s administration, and challenge his judicial and senior government appointments.

The results reflect deep public anger over rising living costs, tariffs, and Trump’s confrontation with Iran, which has driven up fuel prices and amplified frustration with an already deeply unpopular president.
