The United States has withdrawn from GRECO, the Council of Europe's anti-corruption monitoring body, in its latest step away from international groups. GRECO checks its members against anti-corruption standards, from political party financing to rules against bribery. Washington had sat on the panel for years and faced the same peer reviews as everyone else. The move continues a retreat from global institutions that began when the current administration took office. Exits from bodies like the World Health Organization and the UN Human Rights Council came first. Critics see the withdrawal as a signal that Washington no longer wants its own governance held up to outside scrutiny. GRECO's reviews go on without the US, but the panel has now lost one of its most prominent non-European members.
