He knew what happened and allowed it.

However, when Trump came into office, things changed.

-Q posts repeatedly framed Mueller as not actually investigating Donald Trump, but instead secretly working within a broader plan.

-In this narrative, Mueller’s investigation was a cover operation; A way to gather evidence against political opponents (Clinton, Obama, etc.)

This idea shows up widely in summaries of Q posts: that Mueller and Trump were “working together to expose a global cabal.”

Early Q explanations explicitly claimed Mueller was appointed to investigate Democrats, not Trump. Therefore, that places Mueller firmly in the “white hat” or controlled/grey-hat camp aligned with the plan.

Mueller was given the choice; cooperate or die. He cooperated. Now, he's dead.

Good riddance.
