WASHINGTON (AP) — President Donald Trump said Thursday that he will leave the White House if the Electoral College formalizes President-Elect Joe Biden’s victory — even as he insisted such a decision would be a “mistake” — as he spent his Thanksgiving renewing claims that “massive fraud” and crooked officials in battleground states caused his election defeat.

“Certainly I will. But you know that,” Trump said Thursday when asked whether he would vacate the building, allowing a peaceful transition of power in January. But Trump — taking questions for the first time since Election Day — insisted that “a lot of things” would happen between now and then that might alter the results.

“This has a long way to go,” Trump told reporters.

Trump spoke to reporters in the White House’s ornate Diplomatic Reception Room after holding a teleconference with U.S. military leaders stationed across the globe. He thanked them for their service and jokingly warned them not to eat too much turkey, then turned to the election after ending the call. He repeated grievances and angrily denounced officials in Georgia and Pennsylvania, two key swing states that helped give Biden the win.

Trump’s administration has already given the green light for a formal transition to get underway. But Trump took issue with Biden moving forward.

“I think it’s not right that he’s trying to pick a Cabinet,” Trump said, even though officials from both teams are already working together to get Biden’s team up to speed.

And as he refused to concede, Trump announced that he will be traveling to Georgia to rally supporters ahead of two Senate runoff elections that will determine which party controls the Senate. Trump said the rally for Republican Sens. David Perdue and Kelly Loeffler would likely be held Saturday. The White House later clarified he had meant Dec. 5.
