Trump has not been seen in public since his premature declaration of victory in the early hours of Wednesday morning, and the flurry of pronouncements flowing out of the White House ahead of the election has slowed to a trickle.

The presidential race has not yet been called because neither Trump nor Biden has yet collected the requisite 270 Electoral College votes. Some 93% of the state's votes were in by Thursday evening.

Trump has not backed up his claims with any details or evidence, and state and federal officials have not reported any instances of widespread voter fraud.

Mr Biden has since been declared the victor of MI and likely Wisconsin, while nail-biting vote counts involving razor-thin margins have kept America on edge in the other five states. They said it was a "false projection" that Biden would win.

"The Associated Press continues to watch and analyze vote count results from Arizona as they come in", said Sally Buzbee, AP's executive editor.

Speaking at the White House for the first time since Election Night, Mr.

Mr Biden's campaign manager, Jen O'Malley Dillon, said the president "knows he is losing" and had chosen to "push a flailing strategy, created to prevent people's votes from being counted".

After polls closed on November 3 for the 2020 United States presidential election, there are still key battleground states that are counting ballots to help decide a victor between Donald Trump and Joe Biden.

But as more ballots are counted, his lead is rapidly shrinking, with Joe Biden anticipated to take the lead.

As the presidency remained on a knife-edge, Mr Biden used a measured tone to say "democracy is sometimes messy, it sometimes requires a little patience". Several states, including Pennsylvania and North Carolina, were granted extensions to count ballots after Election Day due to the large expected volume of voters who wanted to avoid voting in person due to coronavirus concerns.

"The count is being completed, and we will know very soon", he said at a brief press conference in Wilmington, Delaware, that was also attended by his running mate, Sen.

But the biggest piece of the puzzle remained Pennsylvania, where Trump's early lead was again steadily draining away, as election officials homed in on processing mail-in ballots, which are more typically cast by Biden supporters.

"They want to find out how many votes they need, and then they seem to find them", the president said. "We were up by almost 700,000 votes in Pennsylvania".

Polls this year, similar to the 2016 election that he won, predicted a much weaker electoral performance by Trump than he achieved.

Trump's legal challenges faced long odds.

Asked repeatedly if the United Kingdom wanted the count to continue, the spokesman said: 'That is a matter for the USA'.

Meanwhile, Trump's campaign has filed lawsuits in Pennsylvania, Michigan and Georgia, laying the legal groundwork to contest ballots in the battleground states.

Legislation in several states across the USA calls for the counting of all mail-in votes postmarked by a defined date.
