If a US Pres and VP have not been certifiably elected by 6 January, and if Pelosi is not certified as reelected...the line of succession is Grassley and Pompeo. The US by law must have a President by that date.
As I said, the President Pro Tem serves until another is chosen. The majority party chooses who fills that office. Come January 2nd it will be the Democrats.
