During Mondale's 1967 questioning about what was to become known as the "Phillips Report", Seamans was afraid Mondale might actually have seen a hard copy of Phillips' presentation, and responded that contractors have occasionally been subjected to on-site progress reviews; perhaps this was what Mondale's information referred to. Mondale continued to refer to "the Report" despite Phillips' refusal to characterize it as such, and angered by what he perceived as Webb's deception and concealment of important program problems from Congress, he questioned NASA's selection of North American as prime contractor. Seamans later wrote that Webb roundly chastised him in the cab ride leaving the hearing, for volunteering information which led to the disclosure of Phillips' memo.
