If these accusations are true it would in fact be a treasonous act, however this would a vast conspiracy on a grand scale literally involving thousands of individuals and at least hundreds of main actors who willingly conspired to reverse a democratic election. Trump would need an army of federal law enforcement individuals willing to take down this network and follow its leads to whatever direction it points to. I would presume such a network would by necessity have its own army of law enforcement insiders who were willing to aid and abet such a conspiracy to take place. Let’s be clear Trump doesn’t even have Barr working on his behalf! let alone an army of federal agents willing to prosecute insider individuals who committed this act.
It seems to me, even if the white hats were aware of this, they most likely would be coerced to go along with the publicly reported results of this election because taking down the players involved would mean the end of this government as you know it.
