Some complain that the Mueller investigation has gone on too long. WHOSE FAULT IS THAT?

Every rock that's unturned has tons of critters sliterhing out who have to be followed and tracked and inspected and investigated. Mueller didn't create the rocks or the sleazy slimy slithery creatures. He MUST turn over EVERY ROCK and whatever is under it is fair game. A very rocky man doing very rocky things 24/7.
