HARRISBURG (AP) – Election workers across Pennsylvania are chipping away at over 1 million uncounted mail-in ballots. The nation is awaiting results in a presidential battleground whose trove of 20 electoral votes remained the largest prize yet to be called for President Donald Trump or Joe Biden. The Trump campaign says it filed a lawsuit Wednesday to temporarily stop the count over what it called a lack of transparency. Democrat Gov. Tom Wolf condemned the lawsuit as a “disgraceful” attempt to undermine the election. State officials are counseling patience even as they said a winner might not be known for days.
