First off, it a judge appointed by the Traitor that approved the Search Warrant. Such warrants are not issued if there was sufficient cause for it to be issued.
The FB.I. did inform the Secret Service. The F.B.I. also video taped the search. Merrit Garland would have had to approve the seach as well.
We know that the Traitor removed documents from the WH (At least 15-boxes worth) that should have gone to the National Archives. Which means the Traitor broke federal on that count.
The Traitor also removed classifed documents, Top Secet and above T.S. which means he could be charged with Inproper Handling Classified Material, another Federal Law Broken.
There would not have been a search of the safe without knowing what was in that safe, which means someone other the Traitor told the D.O.J. about the contents of the safe. We know that Mark Meadows has been speaking with the D.O.J. Meadows would have known the contents of the safe
While I am sure Mr. Biden would have to been informed of the search, but he would have no part of it or knowledge of search nor would he have directed the search.
I am laughing my ass off at the totally hair brained and somewhat stupid conspiracy theories I'm reading. But all you people are lies and conspiracies.
