Ambassador

The United States Constitution's section 2 of article 11 and section 2 of article III both use the phrase "ambassadors and other public ministers" to refer to a class of people recognized by international law, which includes diplomatic agents accredited by either the United States or a foreign power to the United States. Their titles have the most meaning in terms of position, seniority, or dignity. Ex parte Baiz, 135 US 403, 34 L Ed 222, 10 S Ct 854, is a good example.
