Trump administration changes have upended the U.S. agency charged with providing humanitarian aid overseas, with senior officials put on leave, contractors laid off and a sweeping freeze imposed on foreign assistance.

The extent of the impacts of the Trump administration’s sudden 90-day freeze of almost all foreign aid is still unclear almost a week on, as officials and aid workers overseas try to make sense of which activities must be suspended.

The 90-day suspension of US aid and “stop-work” requirement following the president’s executive order last week has exposed with lightning-like intensity the global reach of US assistance, whose diverse projects worldwide have been an essential part of American soft power.

The Trump administration’s abrupt freeze on foreign aid has plunged exiled Russian NGOs and media outlets into uncertainty, jeopardizing their funding and posing what some describe as the greatest challenge to Russian civil society since the Kremlin enacted its “undesirable” organization law a decade ago.
