Whether Abercrombie found it or not four years ago is completely and totally irrelevant. Either it is there TODAY or it isn’t and the only way to know for sure is via a judge’s court order or a congressional subpoena.
In 2011 Fox News Channel said that it was stored in the Registrar’s office safe:
“Obama Birth Certificate Moved To A More Secure Location Months Ago:”

You have to take that tack bc you lack the brain power to determine whether Abercrombie actually located the LFBC or not.
