There were at least two insurrectionist plans that day.

As I’ve written previously, one of the plans was simply to either take Pence hostage or to assassinate him. 1/28

That was the more extreme plot, and it is an interesting question whether and to what extent Trump, Giuliani, some WH aides, and some nationalist insurrection members of Congress knew of the plan and either facilitated it or condoned it. 2/28

But there was another plan, less violent and extreme, but equally seditious, which we know was supported by a number of extremist members of Congress. It was also the plan that Trump and his personal lawyer Rudy Giuliani publicly espoused. 3/28

That plan was simply to ensure somehow, by force or by intimidation, that the certification of the election by Congress failed or fell short on January 6--the constitutionally mandated date for the final and determinative certification of the election. 4/28

The principal target here was VP MIke Pence. Pence had already announced publicly that he would not throw the election in the way that Trump had demanded because he lacked the statutory and constitutional authority to do so (which was, of course, perfectly true). 5/28
