Udall also served as New Mexico’s attorney general and served as assistant U.S. attorney before he was elected to the Senate. Biden has nominated a mix of political types and career foreign service officers to a number of ambassador positions since taking office in January. Last month, Biden named former Obama administration official Tom Nides as ambassador to Israel and former Interior Secretary Ken Salazar as ambassador to Mexico. The White House also announced Friday that Biden would nominate three career members of the foreign service to ambassador posts. Biden is nominating Caryn McClelland as ambassador to Brunei, Michael Murphy as ambassador to Bosnia and Herzegovina, and Howard Van Vranken as ambassador to Botswana.
