Some have questioned Roberts' objectivity as a journalist. While working in Guatemala in 1989 helping poor indigenous Guatemalans how to read, Sister Dianna Ortiz, a Catholic nun from New Mexico, was abducted, raped and tortured by members of a government-backed death squad, who believed she was a subversive.[14] During a subsequent interview, Roberts contested Ortiz's claim that an American was among her captors. (The United States provided significant military aid to Guatemala at the time.) Roberts implied that Ortiz was lying about the entire episode, despite the fact that Ortiz later won a lawsuit against a Guatemalan general she accused in the case.[15] It was later revealed that Roberts' brother Tom Boggs' advertising firm Patton, Boggs, & Blow, was paid by the Guatemalan government to promote a more positive image of the regime, which was widely criticized internationally for human rights abuses
