Several senators said 10 witnesses were interviewed for the report. "Fifty pages of an interview is like reading 50 pages of conversation in a book". John Kennedy, R-La., has called an "intergalactic freak show", the calls will likely prove fruitless.

He provided no specifics.
He also said, "I disagree with Sen. Grassley's statement that there was no hint of misconduct".
