If that is information they are suppsed to keep then someone needs to be fired or even criminally charged for failure to keep records, or for destruction of records, regarding the visits.
I’m pretty certain a log is to be kept of all White House visits and phone calls.
One would think that applies when POTUS is elsewhere.
You are Spot On, visitor logs are considered as “official government records” and as such are subject to Federal Law, and Statute that they be kept and preserved as “official records.”
Any US citizen can submit a FOIA request for those records for a specific time period. USSS has three choices, produce the records (no way in hell), declare them “classified” (means they exist), or LIE (which says they violated federal law).
I would guess that ALL middle and upper management in EVERY federal agency in DC is corrupt to some degree. Hannity likes to talk about the 99% of the rank and file is good, that’s BS. My experience is 50% or less is honest and won’t speak up for fear of reprisal. The higher they go the deeper the corruption.
