U.S. Secretary of State Marco Rubio said Wednesday the original intention was to keep the U.S. Agency for International Development running while reviewing how money was being spent. But he said the government received no cooperation and employees were acting in “contravention” and “insubordination.

Secretary of State Marco Rubio, newly in charge of the besieged US Agency for International Development, was for years a staunch supporter of its mission while in the US Senate, reversing his views only recently as President Donald Trump and his allies have moved to dismantle the agency.

The agency is the world's biggest donor, dispensing billions in humanitarian aid and development funding annually.
