Francisco Obadiah Campbell Hooker is the Nicaraguan Ambassador to the United States. He assumed the post in 2010; prior to that he served as deputy to the Central American Parliament. In March 2022, Campbell was also appointed Nicaraguan ambassador to the Organization of American States; he replaced ambassador after McFields denounced the administration of President Daniel Ortega as a "dictatorship" following the arrests and prosecution of a number of opposition figures, some of whom claimed to be "pre-presidential candidates" for the 2021 Nicaraguan general election.
