US president Donald Trump has questioned the honesty of the US midterm elections after previously saying he would accept the sweeping results that favoured the Democrats.

In a new Truth Social post, Trump suggested there were early voting “dumps” and he raised questions about “the machines”.

“Does anybody really believe that this ‘Election’ was honest,” Trump posted early Tuesday (AEST).

“How could the Polls be so wrong???”

He added: “Some early voting ‘dumps’ were so large that it was impossible to win, no matter how many people went to vote.

“It’s all about the machines, which are far more important than the voter!”

There had been fears before the US midterms that Trump and the Republications would react by trying to invalidate results that didn’t go their way.

But as the votes were counted and states flipped from Republican to Democrat across the country, Trump initially appeared to accept the outcome.

“My message is, congratulations to the Democrats, and I look forward to working with you for the good of our country,” Trump told CBS News on election night.

He also told The New York Times he was “absolutely willing” to accept the results and work with the Democrats.

As cutting continues in some tight races, the Democrats have so far won 54 Senate seats and 254 US House seats, giving them majorities in both chambers.

Meanwhile, Trump says he was “kidding” about offering the White House press secretary job to cage-fighting CEO Dana White.

The US President had issued a public plea for White to take on the role but clarified on Sunday that he was only having a “little fun”.

“So I was kidding, but I think Dana likes the idea, and he is a very capable guy,” Trump told reporters.

“Of course, I was kidding. And you could see that because I put all of the great fighters as his assistants, that they’re all going to come with him… It was just a little fun.”

In his social media post on Saturday Trump had implored the UFC boss to fill the post left vacant after Katie Zacharia quit less than five days into the job after a heavily-criticised debut appearance.

“Dana will be a Press Secretary like none other,” the president wrote on Truth social.

“Dana, please take the job!”

Trump described the UFC boss as a “violent fighter and warrior” and requested that he bring several high-profile fighters with him, “even though some are not from our country”.

“We need these people to defend us against the Lunatic Left.”

White later revealed that he would be having a meeting with Trump on Monday.

The 57-year-old had embraced the social media speculation, posting an Instagram photo of himself behind the lectern in the White House press room.

White was a key figure in Trump’s re-election campaign in 2024 but later declared that he wanted “nothing to do with” politics.

Despite that vow he insisted that he was still very much a Trump supporter.
