In Pennsylvania, election officials are counting votes received on or before Nov. 3. Votes received after Election Day are being set aside and not being counted.

The Pennsylvania GOP is asking the Supreme Court to formalize that segregation, even though election officials are already doing so.

President Donald Trump released a statement saying in part, "From the beginning we have said all legal ballots must be counted and all illegal ballots should not be counted, yet we have met resistance to this basic principle by Democrats at every turn...I will never give up fighting for you and our nation."

Mathematically, Trump cannot win another term in the White House without Pennsylvania's electoral votes. Joe Biden has enough of an electoral vote padding that he could afford to lose Pennsylvania and with winning other states, he could still get to the 270 electoral votes.

The counting of votes will continue despite legal challenges.

A recount can be issued for any close states including, Georgia, Nevada, Arizona and Pennsylvania.

That recount, after which Trump would presumably concede if it again is counted in Biden's favor, could go on for several weeks up until potentially Dec. 14. That is when the electors are chosen in the respective states and then sent to Washington, D.C. for the formal vote of the electoral college held in January.

One option in Pennsylvania that has been ruled out is sending a slate of pro-Trump electors to D.C., even if the state goes Biden. The Senate majority leader of the Pennsylvania Statehouse says that is not going to happen.
