This may be a hoax. There are only two occurrences of his name on PACER, and both are discharged bankruptcy cases. Also, the federal inmate locator (http://www.bop.gov/iloc2/LocateInmate.jsp) shows no one by that name.
He said the federal government was paying the jail to keep him. To me that implies that it's not a federal jail. If I remember correctly, I have visited individuals held on federal charges in a county institution.
