Many professions technically have extra responsibilities and limitations. Doctors swear an oath to do no harm and obey a set of rules of conduct. Lawyers are sworn to uphold the law and technically expected to act responsibly. If they violate these rules, they can lose their right to practice their professions.
So why not have rules of conduct for politicians and political appointees? Perhaps add as a requirement that they cannot purposely mislead or lie on TV/video, radio/audio, or in written statements. If they violate that, they must be forced to relinquish their office.
