The former US ambassador to Ukraine, whose abrupt departure has become a focus of impeachment proceedings against Donald Trump, has told congressional investigators that the president personally pressured the state department to recall her as part of a “concerted campaign” against her.
Ambassadors of the United States are persons nominated as ambassadors by the President to serve as United States diplomats to individual nations of the world, to international organizations, and as ambassadors-at-large. Their appointment needs to be confirmed by the United States Senate. An ambassador can be appointed during a recess, but he or she can only serve as ambassador until the end of the next session of Congress unless subsequently confirmed. Ambassadors serve “at the pleasure of the President”, meaning they can be dismissed at any time.
An ambassador may be a career Foreign Service Officer (career diplomat – CD) or a political appointee (PA). In most cases, career foreign service officers serve a tour of approximately three years per ambassadorship
Marie Louise Yovanovitch (born 1958) is a member of the Senior United States Foreign Service who served as the 9th United States Ambassador to Ukraine. She was nominated to the post on May 18, 2016, to replace Geoff Pyatt; was sworn in on August 18, 2016; and was recalled as of May 20, 2019.
Looks like she served her 3 years in post. And it is, even for a career officer, still at the pleasure of the President.
But, you know, Orange Man.
