Now that the Robert Mueller report has been released, showing there was no collusion with the Russians by any American involved with the Republican presidential campaign nor President Trump, the majority of the news media seem unable to let go of their belief this happened, and at a minimum that President Trump committed obstruction of justice warranting impeachment, if not jail, even though criminal wrongdoing was not provable after a two-year investigation by multiple agencies. Is this inability to admit they were wrong, really due to mind control manipulation at the outset to implant actual beliefs that wrongdoing occurred, which cannot be overridden now by common sense or demonstrably factual exculpatory information?

You have hit the nail on the head with this carefully worded question neatly summarizing the conditions and variables in play with this sad tale. It is, unfortunately, the case that this was a contrivance done solely to manipulate human beings in service to the hidden cabal simply wanting to stir up mischief, grow disenchantment, and exacerbate political differences to greatly increase hatred and suspicion for sinister reasons. This is the stock and trade of the interlopers—to create false events and agendas that throw things off track, introduce confusion, and encourage people to engage in make-work projects of all kinds, chasing shadows. That was the case here, and the damage is continuing simply because mind control manipulation was such a prominent component. People whose minds were altered to implant the belief that Trump colluded with Russia, and that he is a servant of Vladimir Putin, cannot simply now change their minds. The ideas have been instilled and are a part of the mind of the person. They are simply unable to change their thinking. Any conflict with their implanted belief will receive the same reaction as a belief that develops naturally. The person will ignore the incoming information and wave it away with the explanation, "It is simply faulty and not worth further scrutiny."
