Caesar's wife must be above suspicion proverb
People who are associated with public figures should avoid doing anything that has a negative impact on that public figure.
A: I heard rumors that our principal's cousin is a criminal. B: No way! That would leave a bad reputation for our school. A: Well, I guess "Caesar's wife must be above suspicion."
This expression came from the story about Julius Caesar and his wife, Pompeia.
A young man named Publius Clodius Pulcher sneaked into Pompeia's party for the purpose of seducing her. This led to Publius’s arrest and trial.
After the trial, Caesar divorced Pompeia. When people questioned if this might have had anything to do with the trial of Publius, Caesar said:
“My wife ought not even to be under suspicion.”
Because Pompeia was suspected of having an extramarital affair, Caesar felt that he had to divorce her to protect his dignity.
