Democratic candidate Joe Biden's chance of winning Pennsylvania roared back to life as mail-in ballots continued to be counted. He was within reach of President Donald Trump in the battleground state early Thursday with thousands of ballots still to count.

Thursday's incoming results are expected to offer more clarity on the tight-knit race. Biden currently leads with 264 electoral votes to Trump's 213, and 270 electoral votes are needed to win the presidency, AP reports.

If the former vice president wins Pennsylvania, the race will be over, as Biden would collect Pennsylvania's 20 electoral votes. Thousands of votes remain uncounted so far in the key swing state while the former vice president is behind by just over 115,000 votes as of 12:30 p.m. EST on Thursday.

It is not clear how many votes still need to be tallied in Pennsylvania.

Pennsylvania’s Lt. Gov. John Fetterman, a Democrat, told CNN that Keystone State results could come Thursday and that he believed outstanding ballots in the swing state favor, Biden.

The Biden campaign seems optimistic about the possibility of winning Pennsylvania. Biden campaign manager, Jen O'Malley Dillon, said the campaign is "confident" that they will win Nevada and Pennsylvania.

Trump angrily lashed out at the ongoing counts in Pennsylvania and urged pollsters to stop counting votes.

“STOP THE COUNT!” Trump tweeted.

In an additional tweet, Trump falsely suggested that ballots counter after Nov. 3 would be discarded. Twitter flagged the misinformation, noting that ballots still need to be counted.

GOP lawyers are seeking to halt the counts in Pennsylvania and elsewhere with lawsuits.

The Trump campaign will ask the Supreme Court to intervene in a case that challenges the Pennsylvania Supreme Court decision to allow the counting of ballots after Election Day.

“The time has come. Given last night’s results, the vote in Pennsylvania may well determine the next President of the United States,” Trump's lawyer Jay Sekulow said in the new filing.

“And this Court, not the Pennsylvania Supreme Court, should have the final say on the relevant and dispositive legal questions," Sekulow said.
