United States President Donald Trump renewed baseless allegations of voter fraud on Monday, questioning the legitimacy of last week’s midterm elections after Democrats swept both chambers of Congress in a crushing defeat for his Republican Party.

“Does anybody really believe that this ‘Election’ was honest. How could the Polls be so wrong???” Trump wrote on Truth Social, alleging without evidence that large early voting “dumps” had made Republican victories impossible.

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

Chuck Schumer, the top Democrat in the US Senate, has said, “Donald Trump’s pathetic return to election denialism was inevitable.

“He can whine all he wants, but nothing will stop this inescapable truth: For the last two years of his presidency, Trump will face the largest Democratic congressional majorities in decades, all because he has been an unprecedented failure.”

The accusations marked a sharp reversal from Trump’s initial acceptance of the results.

“I am absolutely willing to accept those results,” he told The New York Times on election night.

The president has repeatedly made unfounded claims of election fraud, most notably following his defeat by Joe Biden in the 2020 presidential election.

In the Nov 3 midterm elections, Democrats seized control of the US Congress, capturing the Senate and House of Representatives in a stunning, nationwide rejection of Trump.

The result was a personal humiliation for the 80-year-old Trump, leaving him as a lame duck president for the remaining two years of his term and signalling an end to his stranglehold on the Republican Party.

He had previously attempted to brush off the election results, spending the beginning of his first public appearance on Wednesday talking to reporters about the marble and Corinthian columns of his new $400 million ballroom.

But he conceded that what Vice President JD Vance said about the Iran war being a factor was “largely true because it drove the gasoline up” — a key issue for voters angered by the rising cost of living.

Still, Trump defended his war against Iran, saying: “But at the same time, if I had it to do again, I’d have to do it again. Because long term, it’s the only answer. You can’t let Iran have a nuclear weapon.”

On Sunday, Trump vowed to bounce back stronger from the midterm election loss that he called a “giant step back in history” for the US.
