Nothing happening is outside the plan. Mueller's investigation in Russian involvement ended and it was revealed Hillary worked with the Russians in the 2016 election. The impeachment on charges that Trump extorted Ukraine revealed Biden was extorting extorting Ukraine. So what do you think will be revelead in a trial that accuses Trump of insurrection and causing the Capitol riots?
Will establishment insurrection soon be proved?
OP: Please refine your last sentence. They are accusing Trump of "insurrection". This mean they are the party guilty of insurrection.
If the impeachment trial is about the capital riots than all the evidence will show it was antifa and the guards let them in and so on. Why the hell would any trial let you bring up points that have nothing to do with the actual impeachment. Ukraine, clintons nothing is relevant in this trial.
Most likely Antifa and Capitol cops did not act alone. Many in Congress were most likely involved in the planning.
Will the trials reveal this?
Nothing will happen at the impeachment. They won't let anybody introduce evidence. They would just vote. You think they would do all this to Trump just to let him introduce evidence at an impeachment trial?
