If the police obtain a warrant to raid your house during a fraud investigation but instead they find 1000 tons of crystal meth in your basement then they are allowed to refer that to a new investigation. It's not deemed inadmissible on the basis it was found during the course of a different investigation.

Obviously I am not a lawyer but it seems fantasy law people have invented on twitter that anything else Mueller finds outside of his remit in ineligible for investigation.

Nailed it.
