PanThe Washington PostSiege is ultimately crippled by three flaws: Wolff’s overreliance on a single character, and one who is now more distant from the action; factual errors that mar the author’s credibility; and sourcing that is so opaque it renders the scoops highly suspicious and unreliable ... Wolff’s obsession with documenting Bannon’s every thought, while remaining uninterested in the reality of the racial politics unleashed by him and Trump, reaches peak hilarity when he earnestly quotes Bannon’s dissection of whether the president is an anti-Semite (probably not) or a racist (probably) ... the idea that Wolff is documenting some larger ideological struggle in the Trump GOP is mostly familiar Bannon spin ... Wolff’s broad conceptual error — that the real heart of Trumpism is heroically being kept alive by Bannon’s band of true-believing outsiders — would be forgivable if the book wasn’t marred by two more strikes: some cringeworthy errors, and sourcing that is so opaque it renders the extremely fun and juicy quotes sprinkled across every chapter as — sadly — difficult to trust. Wolff reports that he had two fact-checkers assigned to the book, but they apparently weren’t enough ... Wolff clearly relies on the work of dozens of other reporters on the Trump beat, but because he rarely uses any attributions, the reader never knows whether a fact he’s relaying comes from him or elsewhere.
