The US state department is preparing to shut down a number of consulates that are mainly in western Europe in the coming months and looking to reduce its workforce globally, multiple US officials said on Thursday.

The state department is also looking into potentially merging a number of its expert bureaus at its headquarters in Washington that are working in areas such as human rights, refugees, global criminal justice, women’s issues and efforts to counter human trafficking, the officials said.

Reuters reported last month that US missions around the world had been asked to look into reducing US and locally employed staff by at least 10% as Donald Trump and his billionaire aide Elon Musk have unleashed an unprecedented cost-cutting effort across the US federal workforce.

The Republican president wants to ensure his bureaucracy is fully aligned with his “America first” agenda. Last month he issued an executive order to revamp the US foreign service to ensure “faithful and effective” implementation of his foreign policy agenda.

During his electoral campaign, he had repeatedly pledged to “clean out” what he refers to as “the deep state” by firing bureaucrats that he deems disloyal.

Critics say the potential cuts in the US diplomatic footprint coupled with the dismantling of the US Agency for International Development (USAid) that provided billions of dollars worth of aid globally risk undermining American leadership and leaves a dangerous vacuum for adversaries like China and Russia to fill.

Trump and Musk say the US government is too big and American taxpayer-funded aid has been spent in a wasteful and fraudulent way.

Leipzig, Hamburg and Dusseldorf in Germany, Bordeaux and Strasbourg in France, and Florence in Italy were among a list of smaller consulates that the state department is considering shutting down, three officials said, adding that could still change as some staff were making a case for them to stay open.

Officials said the department on Monday had notified Congress that it plans to shutter its branch in Turkey’s south-eastern city of Gaziantep, a location from which Washington has supported humanitarian work in northern Syria.

“The state department continues to assess our global posture to ensure we are best positioned to address modern challenges on behalf of the American people,” a state department spokesperson said.

The department operates in more than 270 diplomatic missions worldwide with a total workforce of nearly 70,000, according to its website.
