Juan Guaidó
The Organization of American States (OAS) made a decision on 10 January 2019 "to not recognize the legitimacy of Nicolas Maduro's new term".  Luis Almagro, Secretary General of the OAS, recognized Guaidó on 23 January. In a special meeting of the OAS on 24 January, sixteen countries, including the US, recognized Guaidó as president, but they did not achieve the majority needed for a resolution.
