President Donald Trump has suffered one of the most significant political defeats of his second term following the November 3 midterm elections.

Democrats won control of both chambers of Congress, ending Republican dominance in Washington and delivering a powerful rejection of the president's political agenda.

Voter frustration over rising living costs, the war with Iran and concerns about government corruption played a major role in the election results.

Democratic victories extended into traditionally Republican states, including Texas and Kansas.

The outcome threatens to significantly restrict Trump's political influence during his remaining two years in office. Democratic leaders are preparing to strengthen congressional oversight and investigate controversial administration decisions.

Although Trump remains president, his ability to advance legislation and secure political support in Congress faces substantial new obstacles.
