She is just following the advice of Sir Humphrey Appleby in Yes Minister:
Sir Humphrey: In stage two you go on to discredit the information you’re not publishing.
Jim Hacker: How, if you’re not publishing it?
Sir Humphrey: It’s much easier if it’s not published. You do it by press leaks. Say it leaves some important questions unanswered, that much of the evidence is inconclusive, that the figures are open to other interpretations, that certain findings are contradictory and that some of the main conclusions have been questioned.
Jim Hacker: Suppose they haven’t?
Sir Humphrey: Then question them. Then they have.
Jim Hacker: But to make accusations like that you’d have to go through it with a fine-toothed comb.
Sir Humphrey: Nonsense – you can say all that without reading it. There are always some questions unanswered.
Jim Hacker: Such as?
Sir Humphrey: The ones that weren’t asked.
