The NY Times broke the secret memo story and has the details.

The memo had been a missing piece in the public record of how Mr. Trump’s allies developed their strategy to overturn Mr. Biden’s victory. In mid-December, the false Trump electors could go through the motions of voting as if they had the authority to do so. Then, on Jan. 6, 2021, Vice President Mike Pence could unilaterally count those slates of votes, rather than the official and certified ones for Joseph R. Biden Jr.

Step one, create some fake electoral votes. Step two, put Mike Pence alone in a room so that he can count the fake ones. Success!

While that basic plan itself was already known, the document, described by prosecutors as the “fraudulent elector memo,” provides new details about how it originated and was discussed behind the scenes. Among those details is Mr. Chesebro’s proposed “messaging” strategy to explain why pro-Trump electors were meeting in states where Mr. Biden was declared the winner. The campaign would present that step as “a routine measure that is necessary to ensure” that the correct electoral slate could be counted by Congress if courts or legislatures later concluded that Mr. Trump had actually won the states.

But present it that way to whom? Presenting it that way to the public is one thing, but surely there are people in charge who would tell Chesebro and Trump and all of them that no it is not a routine measure, get out of here, if you try it again we’ll Lock You Up. In other words I don’t quite get how that would work in practice. But then it didn’t work in practice, so maybe that’s the answer.
