Trump, a Republican who lost the November presidential election to his Democratic counterpart, has not conceded to Biden, and he spent part of his rally remarks in Dalton, a city in Georgia's heavily Republican northwest, suggesting that he would try to hold on to power.
The outgoing president also put pressure on Vice President Mike Pence, who will receive the results of the state-by-state Electoral College in Congress on Wednesday, to take action in his favor. Biden beat Trump 306-232 in electoral votes and carried the popular vote by more than 7 million ballots.
"I hope Mike Pence comes through for us," Trump said, referring to the vice president as a great guy. "If he doesn't come through, I won't like him quite as much," Trump said.
Long a solidly Republican state, Georgia surprised the nation in November by choosing Biden, the first time it had backed a Democratic presidential candidate in almost three decades.
