According to Bloomberg, del Castano wrote articles for the Spanish-language news website The Objective containing strong rebukes against Trump and Spanish Prime Minister Pedro Sánchez. In one post, he criticized the president's "poor manners, his self-centeredness, his apparent lack of scruples, and his morally questionable nature," Bloomberg reported. When the publication went to Goldman for comment, the bank said it had not been aware of the articles, which The Objective then deleted.
