The validity of Werfel's office seems highly questionable (i.e. is he a 'firewall'?). I would direct all related correspondence to the Treasurer of the United Staets, to the Secretary of the Treasury and to Christopher J. Meade, Chief Counsel, U.S. Department of the Treasury and cc: the State AG, the U.S. district attorney or the chief justice of whatever U.S. district court office is nearest you. Regarding demanding that the law be followed -> writ of mandamus. These days when i see "Acting {anything}" I'd tend to look up the organization chart or look for a deputy or departmental counsel to include in case the "Acting {anything}" is a 'firewall' (without bond, proper oath or office).
Off the top, usually notaries are prohibited from notarizing something to which they are a party. If you want to make a 'bulletproof package', I'd go to the county clerk or whoever the official is to get a certified copy.
