This time he was going to have cover if it happened again. He didn't release the tape until Trump tweeted another false accusation of their conversation. Trump tends to use the bully pulpit and this time it backfired.
I don't think he will be charged for this and the other investigations may even slip away. I wouldn't be surprised if Biden and Trump work out a quid pro quo pardon deal for him to disappear.
As for hanging on his words, you are right. But he is a bully and I enjoy seeing him getting his comeuppance.
