In an odd way, this is good news.
What this tells us is: They did not find what they were looking for, which was the files Trump has on the DOJ’s illegal attempts to charge Trump.
The claim that Trump is hiding confidential and/or secret files is a claim to support a request for a warrant to search again or to search other sites. Such a search will be with a warrant permitting a search for classified files but will be used in fact to search for files Trump intends to use in legal action against the DOJ and its thugs in the FBI.
The files must be powerful stuff judging by the panic the DOJ is exhibiting.
Get more popcorn and a nice comfortable chair. There is about to be a good show.
That’s what it sounds like...that they’re after something specific.
I was thinking the same thing. They were likely looking for something very specific and incriminating he had that shows how the US government, specifically the FBI/DOJ, had abused his power to try to harm his candidacy or presidency and they wanted it back and used something like the nuclear secrets excuse to get in there.
