Trump spoke on Monday about the transition of power to Biden, so if that isn't a concession of defeat, then what is?
Actually making a concession speech.
Saying he'll allow his team to work with a transition team in the same breath as saying he's continuing to fight isn't a concession. While it is still being contested by him it isn't an official result until the Electoral College decide it, whatever low percentage chance people think he has of success.
Its' the 8th of December when is the final deadline for resolving election disputes. Sir, can you confirm this is the latest day we can achieve our bets? Waiting till the inauguration day on the 20th of January would be nonsense as we all know Trump will never concede.
