Impersonation of a Goodwill Ambassador
There are many criminal statutes that protect the "Goodwill Ambassador" title. Most states and local jurisdictions generally consider false personation a misdemeanor, except when impersonating a peace officer which is a felony in most jurisdictions. Under Federal Law however, it is a felony to impersonate a US citizen, a US government employee, a creditor, a member of a diplomatic corps, an agent or member of the 4-H Club, or a member of the Red Cross which is punishable by a term of 3-10 years and fines from $1,000 to $50,000 USD per incident, higher fines can be assessed. Title 18 of the U.S. Code Chapter 43 covers the crime of "False Personation" under §§ 911 - 917.
Title 25 of the US Code of Federal Regulations § 11.432 - Impersonating a public servant. A person commits a misdemeanor if he or she falsely pretends to hold a position in the public service with purpose to induce another to submit to such pretended official authority or otherwise to act in reliance upon that pretense to his or her prejudice.
Kentucky Revised Statutes § 519.050 - In Kentucky there is a law that prevents any person from impersonating a public servant other than a police officer, Kentucky Revised Statutes § 519.050 can be interpreted to mean a Kentucky Colonel, a Notary Public, any state employee, a forestry officer, a tax collector or even a rest-stop maintenance worker. Most states have similar laws that can be very conservatively interpreted and translated.
