Washington DC - Donald Trump is "still your president," the White House said Wednesday, a day after his Republican Party suffered sweeping losses in midterm elections seen as a referendum on his second term.

The White House delivered the message in a post on X featuring a picture of a glaring Trump looming over the Resolute Desk in the Oval Office.

"PSA: TRUMP IS STILL YOUR PRESIDENT," text superimposed on the image said, using the abbreviation for public service announcement.

"Thank you for your attention to this matter," the post added, using a phrase Trump frequently employs in his social media messages.

Opposition Democrats won control of both the House and the Senate on Tuesday, dealing a major blow to Trump and the Republican Party.

The Democratic capture of Congress signals an end to Trump's stranglehold on US politics and gives Democrats the power to pass legislation, launch investigations into Trump's administration and thwart his appointments.

The results reflected deep frustration over the cost of living, tariffs, and Trump's war with Iran, which has sent prices soaring and compounded dissatisfaction with an already deeply unpopular president.

But Trump has threatened to use his veto power, raising questions about how much Democrats can achieve even with control of both the House and Senate.
