It turns out that...
Trump fired Comey.
Comey sought help, not to investigate Trump’s firing of him or Trump’s attempted intervention to block the Trump/Putin collusion, which Comey knew was a fable.
Comey needed and sought help in trying to cover up his butt and that of the FBI’s. because, of their collusion with the Hillary campaign and the help of the DNC and the Obama administration, in fabricating the fusionGP phony dossier about Trump/Putin collusion to steal the election.
Comey was desperate, and sought the help of his friends, and one of those big friends was/is Mueller. Mueller is in the midst of one of he biggest crimes in U.S. history, that being the attempted removal of a duly elected president. Mueller had to know, and if not, he surely has known for a while now that the Trump/Putin collusion story was a blatant lie, and collusion to remove a president. Who can doubt that Mueller is part of the conspiracy from the start?
Third sentence should read:
Comey sought help, not to investigate Trump’s firing of him or Trump’s attempted intervention to block the Trump/Putin collusion investigation, which Comey knew was a fable.
