Workers at the US Agency for International Development (USAID) headquarters in Washington got a surprise early Monday morning when they were told not to come into the office. An email sent shortly after midnight said the main office would be closed and staff should work from home instead—except for a few essential employees who were personally contacted.

The sudden move has raised eyebrows, especially after reports that USAID’s funding was recently frozen and dozens of employees were placed on leave. Adding to the intrigue, logos and photos showcasing the agency’s global humanitarian efforts were taken down from its offices last week.

While the exact reason for the closure remains unclear, some insiders suggest it might be linked to broader discussions about the agency’s future. Tech mogul Elon Musk hinted that President Trump has previously called for USAID to be “shut down.”

As the situation unfolds, employees and observers are left wondering what’s next for the agency. Stay tuned for updates as this story develops.
