Zippy, their "plan" was to go to war with Antifa at the Capitol to provide Trump the cover to invoke the Insurrection Act...
The President, by using the militia or the armed forces, or both, or by any other means, shall take such measures as he considers necessary to suppress, in a State, any insurrection, domestic violence, unlawful combination, or conspiracy, if it--
(1) so hinders the execution of the laws of that State, and of the United States within the State, that any part or class of its people is deprived of a right, privilege, immunity, or protection named in the Constitution and secured by law, and the constituted authorities of that State are unable, fail, or refuse to protect that right, privilege, or immunity, or to give that protection; or
(2) opposes or obstructs the execution of the laws of the United States or impedes the course of justice under those laws.
So they planned on an "insurrection" hoping Trump would invoke the above and name them as the militia called upon by the president.
It didn't work because Antifa never showed up as they had hoped.
