UN Secretary-General António Guterres seems to be bracing his staff ahead of possible changes in U.S. foreign policy under President Donald Trump. In a letter distributed to UN staff, Guterres warned of the “difficult challenge” facing the international body.

“I assure you that we are working closely with colleagues throughout the United Nations system to understand and mitigate the extent of its impact on our operations,” Guterres wrote in the letter.

“Now, more than ever, the work of the United Nations is crucial. As we face this difficult challenge, your dedication and support will help us to overcome and move forward. Together, we will ensure that our Organization continues to serve people in need around the world with unwavering commitment.”

In response to a Fox News request for comment, Guterres’ spokesperson Stéphane Dujarric said, “From day one, US support for the United Nations has saved countless lives and advanced global security.  The Secretary-General looks forward to continuing his productive relationship with President Trump and the US Government to strengthen that relationship in today’s turbulent world.”

During his 2024 campaign, Trump took aim at government spending, ultimately introducing DOGE to tackle waste.

Following Trump’s order, Secretary Rubio paused all US foreign assistance programs funded by or through the State Department and USAID pending review.

“Reviewing and realigning foreign assistance on behalf of hardworking taxpayers is not just the right thing to do, it is a moral imperative,” the State Department statement read. “The Secretary is proud to protect America’s investment with a deliberate and judicious review of how we spend foreign assistance dollars overseas.”

In the same statement, the State Department emphasized Secretary Rubio’s focus on ensuring the programs his department funds are working for Americans and are “consistent with US foreign policy under the America First agenda.”
