Trump is finally admitting he lost the 2020 election

Was that when

Donald Trump tweets: “Mike Pence didn’t have the courage to do what should have been done to protect our Country and our Constitution, giving States a chance to certify a corrected set of facts, not the fraudulent or inaccurate ones which they were asked to previously certify. USA demands the truth!”

Or do you mean the video he posted a few hours later where he continued to insist the election was 'stolen'

"I know your pain. I know your hurt," he said. "We had an election that was stolen from us. It was a landslide election and everyone knows it, especially the other side. But you have to go home now."

What did he say on January 6th?

Edit: So I had seen clips and read lots of articles about what Trump said on January 6th, but I had never read the transcript. So I thought, why not? Let's see it without anyone else telling me what it says. Holy shit, it was so much worse than I thought.

No he didn't.
