Tom Wolf, Governor of Pennsylvania, said via Twitter that there are still over one million votes left to be counted. He said that he is going to deliver on his promise of counting every vote. Those remarks likely related to Trump's speech, in which he claimed counting should end to avoid fraud, as Tom Wolf labelled it a partisan attack on elections. Pennsylvania is one of the key states as 20 electoral votes are at stake there. According to the latest data from NPR, Trump leads 56-43 in Pennsylvania with estimated 64% of the votes counted.
