A few minutes later, he followed it up with the claim that the state of Nevada was "turning out to be a cesspool of Fake Votes" and that officials were "finding things that, when released, will be absolutely shocking!"
Trump provided no details or evidence to support his comments, and Twitter slapped the tweet with the warning that "this claim about election fraud is disputed".
Less than 10 minutes later, Trump was back on his favourite social media platform, claiming the state of Wisconsin – which has already been called for Democratic nominee Joe Biden – was looking positive for the Republican Party.
"Wisconsin is looking very good. Needs a little time statutorily. Will happen soon!"
Then, 15 minutes later, it was Pennsylvania's turn, with Trump alleging the state, which has also gone Biden's way, stopped Republicans from monitoring the vote count.
"Pennsylvania prevented us from watching much of the Ballot count. Unthinkable and illegal in this country," he posted, with the tweet again accompanied by an official Twitter warning.
Just four minutes later, he issued his final tweet – for now – claiming "Georgia will be a big presidential win, as it was the night of the Election!"
At the moment, Georgia is still to be called, but Biden is narrowly leading there with 49.5 per cent of votes compared with Trump's 49.3 per cent, with 99 per cent of votes already counted.
Georgia will hold a recount as soon as the first vote count is concluded.
Meanwhile, the Trump campaign has insisted the President is "not backing down", with campaign manager Bill Stepien urging Republican Party supporters to have "patience", according to Fox News.
Stepien told staffers to wait for the results of legal battles which have been launched in a number of crucial states where Biden narrowly leads, including Arizona, Nevada, Pennsylvania and Georgia.
"He still is in this fight," Mr Stepien said. "There is a process."
Yesterday, CNN reported that several members of the President's own family – including wife Melania Trump and son-in-law and adviser Jared Kushner – had privately urged him to concede defeat graciously.
But Trump is still refusing to accept the results of the election, which saw him lose the popular vote to Joe Biden by more than 4.5 million votes so far.
More importantly, Trump has received just 214 electoral college votes compared with Democratic Party nominee Joe Biden's 290.
To win a US election, a candidate must secure a crucial 270 electoral college votes to claim victory, and while three states – Alaska, Georgia and North Carolina – are still counting, they would not make a difference to the final result.
Trump has repeatedly, and with no evidence, insisted his Democratic Party rivals were trying to "steal" the election and made baseless allegations of voter fraud.
