Final answer:
The attorney likely violated the duty of confidentiality by disclosing a client's previous marriage and divorce without consent. Maintaining client confidentiality is a core ethical obligation for attorneys, critical to the integrity of the legal profession.
Step-by-step explanation:
The question pertains to whether an attorney violated the duty of confidentiality by disclosing information about a client's previous marriage and divorce in a public forum. The duty of confidentiality is fundamental in the attorney-client relationship, designed to protect client's private information unless specific, informed consent is given.
By sharing this information in comments to news media, without the client's explicit permission, the attorney potentially breached this duty unless an exception to confidentiality applied, which is not indicated in the scenario provided. Attorneys must maintain confidentiality of all information related to the representation of their clients, as per the American Bar Association's (ABA) Model Rules of Professional Conduct.
