The American Foreign Service Association said it had received “credible reports from our members in diplomatic posts around the world that multiple career ambassadors, appointed during the Biden administration, have been directed by phone call to vacate their posts by January 15 or 16”.
“No explanation was given for these recalls,” the association added in its post on Facebook.
“Removing senior diplomats without cause undermines US credibility abroad and sends a chilling signal to the professional Foreign Service: experience and an oath to the Constitution take a backseat to political loyalty,” it said.
A senior State Department official said on Monday that changing ambassadors was “a standard process in any administration”.
“An ambassador is a personal representative of the President, and it is the President’s right to ensure that he has individuals in these countries who advance the America First agenda,” the official said on condition of anonymity.
The official did not confirm the details of the dismissals, or which countries were affected.
In his second term, President Donald Trump and his Secretary of State, Marco Rubio, have overhauled American diplomacy to focus priorities such as combating illegal immigration, cutting foreign aid and diversity policies.
Rubio has overseen the dismissal of hundreds of personnel within the State Department, and Trump has placed loyalists as key ambassadors.
