who holds the privilege when it concerns attorney-client communication
Attorney–client privilege In the law of the United States, attorney–client privilege or lawyer–client privilege is a "client's right privilege to refuse to disclose and to prevent any other person from disclosing confidential communications between the client and the attorney."[1]
Brendan Sullivan Sullivan shot to national prominence in 1987, when he represented Oliver North in televised congressional hearings over the Iran-Contra scandal. During the hearings in front of the Joint House–Senate Iran-Contra Committee, chairman Daniel Inouye suggested that North speak for himself, admonishing Sullivan for constantly objecting to questions posed to North. Sullivan famously responded, "Well, sir, I'm not a potted plant. I'm here as the lawyer. That's my job." Furthermore, apparently he "shouted down a question" that he claimed violated attorney-client privilege: “That’s none of your business either!”[1] Sullivan received international media attention as the episode was broadcast on live television, making him "something of a hero to lawyers, even moderates and liberals".[4] The trial showcased his "confrontational style of 'protecting the client at any cost'" that has proven to be "extremely effective" despite angering several congressmen.[2]
