Pro Tip: If she had accepted the buyout they would then have the material to blackmail her at a later date.

Damn, that is a great observation.

I assumed she recorded it and leaked it.

Now that you mention it, maybe someone else was conspiring with DeWit to secretly record it, so they could have blackmail material on her.

But ... then why would the leak it now?

No evidence that she accepted.

Whoever leaked this did so to go after DeWit.

It never ceases to amaze what dirty scum infest the arena of politics.
