WASHINGTON -  Democrats have seized control of both chambers of the US Congress in a sweeping midterm election victory, delivering a major rebuke to President Donald Trump and threatening to derail his legislative agenda during the final two years of his presidency.

The Democratic gains in the Senate and House of Representatives will give the opposition significant power to block legislation, investigate the Trump administration and obstruct judicial and senior government appointments.

The results reflect widespread voter dissatisfaction with rising living costs, tariffs and Trump's war against Iran, which has driven up fuel prices and intensified economic pressures.

Trump adopted a conciliatory tone after the defeat, telling The New York Times he was "absolutely willing to accept those results" and promising to work with Democrats.

"I think the Democrats did a good job, I really do," he told Fox News, while insisting the results were not a personal setback.

However, Trump acknowledged that the Iran conflict had contributed to the Republican defeat and later posted an image of a red baseball cap bearing the word "VETO," signalling his intention to resist Democratic legislative efforts.

- Historic Democratic gains

Democrats made significant breakthroughs in traditionally Republican states, including Kansas and Iowa, where they captured Senate seats for the first time in decades.

In Kansas, Methodist minister Adam Hamilton defeated Republican incumbent Roger Marshall, becoming the state's first Democratic senator since 1932. Iowa also elected a Democratic senator for the first time since 2008.

The victories followed Democratic gains in Texas, South Carolina, North Carolina and Ohio, despite Trump's efforts to mobilise Republican voters.

In Texas, James Talarico defeated Trump-backed candidate Ken Paxton in the Senate race, while Gina Hinojosa defeated Republican Governor Greg Abbott, ending decades of Republican control of the state's top office.

Democrats also captured governorships in Georgia and California. Former Atlanta mayor Keisha Lance Bottoms became the first Black woman elected governor in US history, while former Biden administration official Xavier Becerra won California's governorship.

Republicans retained some victories, including Byron Donalds' election as Florida governor and Ashley Moody's Senate win.

- Trump faces congressional scrutiny

The Democratic takeover will allow the party to launch investigations into the administration's handling of the Iran war, immigration enforcement and corruption allegations.

House Democratic leader Hakeem Jeffries is positioned to become the first Black speaker of the House when the new Congress convenes in January.

The election also highlighted widespread frustration with the economy. Rising rents, grocery prices, utility bills and property taxes were major concerns for voters.

Exit polls indicated that half of voters viewed the election as an opportunity to rebuke Trump, while 70% wanted Congress to impose stronger checks and balances on the president.

The results underscore the historical tendency for the president's party to lose congressional seats in midterm elections, but the scale of the Democratic victory presents an especially serious challenge to Trump's political standing and governing agenda.
