They’re backed up by some etiquette experts. The bible of all things correct, “Emily Post’s Etiquette,” allows that the title “The Honorable” “causes considerable confusion.” But it decrees that a White House aide, with the title of assistant to the president and communications director for the Office of Public Liaison, isn’t entitled to it. The honorific is reserved for “the President, the Vice President, United States senators and congressmen, Cabinet members, all federal judges, ministers plenipotentiary, ambassadors, and governors,” who get to use the title for life. State senators and mayors are “The Honorable” only when in office.
Still, even if Omarosa was eligible to be addressed as “The Honorable,” Emily Post decrees that it’s unseemly for anyone to refer to themselves that way.
“The title is not used by the person on visiting cards, letterhead, or when signing, nor does one say it when introducing him- or herself.”
