Donald Trump claimed on Wednesday morning he was winning Pennsylvania by a “tremendous amount” with the fate of both campaigns hanging on the key state.
But with 95 per cent of votes counted, Mr Trump is leading over Joe Biden with 49.5 per cent to 49.2 per cent.
Democrats have pointed to the fact that the state’s postal vote count was not complete, with Mr Biden expected to pick up a majority of those votes in the state.
In Pennsylvania, ballots postmarked by November 3 can be accepted if they arrive up to three days after the election.
The state carries 20 electoral college votes, which both camps are relying on to get over the 270-vote mark needed to win the election.
In his address in the early hours of Wednesday morning, Mr Trump said he was asking the Supreme Court to suspend the count.
Pennsylvania’s Democratic Governor Tom Wolf called Mr Trump’s unsubstantiated claim about fraud in the US presidential election a “partisan attack”, and said his state was working hard to count more than one million mail-in ballots.
“Let’s be clear: This is a partisan attack on Pennsylvania’s elections, our votes, and democracy,” Mr Wolf said in a tweet. “Our counties are working tirelessly to process votes as quickly AND as accurately as possible. Pennsylvania will have a fair election and we will count every vote.”
Kathy Boockvar, Pennsylvania’s Secretary of State, said at a press conference on Friday morning that there are “several-hundred thousand” ballots left to count but they are in the “home stretch” of the count.
She went on to urge people to “stay tuned” as the “overwhelming majority of ballots will be counted by Friday”. Military and overseas ballots will be counted by Tuesday.
However, Ms Boockvar stressed that she is confident in the integrity of the election and that she is “not aware of any recent allegations of voter fraud”.
“It’s very close in Pennsylvania, which means it’s going to take longer to see,” said Ms Boockvar.
“I can say there are several-hundreds thousand ballots remaining to be counted. The closer the race is, the longer it takes. Because it’s so close, it’s not yet clear who the winner is.”
