Criminal defense
attorneys have a duty to zealously represent their clients and protect their confidences. However, they also have a duty before the court not to present evidence that they know is false, fraudulent, or perjury, whether it comes from the defendant or from a witness that the lawyer knows intends to lie.A lawyer who knowingly uses or gives perjury testimony risks serious consequences. Under the profession's code of ethics (the Canons of Professional Ethics of the American Bar Association), doing so subjects the lawyer to discipline and, quite possibly, disqualification.

If the client insists on falsely testifying, the lawyer must refuse to offer the perjury testimony or must immediately request that he withdraw from the representation. The lawyer should further explain that he may be required to disclose the client's intentions to the court, if the court requires the lawyer to disclose a specific reason for the withdrawal.

As for the last two questions, if lawyers play a special role in telling the truth and what are the lies that fall outside the protection of the First Amendment in a world where sources cannot be trusted and lies abound, the legal profession distinguishes itself in an important way. According to the Preamble to the Model Rules, lawyers must constantly balance their duties as “a representative of clients, an officer of the legal system, and a public citizen who has a special responsibility for the quality of justice. Pro-Trump lawyer Tom McCarthy says “no reasonable person” would believe his election lies, Guardian (March) Ethics rules can and should be protective barriers to protect against future lies from lawyers who understand valid election results.
