Is It Related to the Fake Elector Scheme?

Is there a way for us to discern if this search warrant being effected at mister clark's house is related to the fake elector scheme, or if this is a public sign of some other federal criminal investigation that we don't yet know about? It does seem that if you're going to do all these events on the same day, oftentimes you do that because you don't want one to tip off the other. But the fact that they have taken this overt step, and that they had sufficient evidence to show to a judge that they had probable cause to believe a crime has been committed suggests to me that we're closer to the end than the beginning of an investigation.
