The U.N. Committee on the Elimination of Racial Discrimination issued its call to action though an "early warning and urgent action" procedure. The panel comprises what the United Nations calls "18 independent experts who are persons of high moral standing and acknowledged impartiality".
It recommends that the US government "identify and take concrete measures to address the root causes of the proliferation of such racist manifestations, and thoroughly investigate the phenomenon of racial discrimination targeting in particular against people of African descent, ethnic or ethno-religious minorities, and migrants" as well as "ensure that the rights to freedom of expression, association and peaceful assembly are not exercised with the aim of destroying or denying the rights and freedoms of others, especially the right to equality and non-discrimination, and that the Government of the United States of America provide the necessary guarantees so that such rights are not misused to promote racist hate speech and racist crimes".
