The Trump administration's Justice Department is prosecuting former FBI director James Comey for allegedly threatening to kill the president — and part of its evidence is a novel Comey wrote. The charge stems from an Instagram photo of seashells arranged to read '8647,' posted five days before publication of his book FDR Drive. Prosecutors argue the number combines restaurant slang for 'get rid of' (86) with Trump's presidential number (47), constituting a transmitted threat across state lines. The government's May 2025 filing goes further than the seashell photo. Prosecutors quote passages from FDR Drive — whose fictional protagonist, a federal prosecutor, targets a far-right media personality — and a Publishers Weekly review describing the character's belief that his enemy 'went far beyond the protection of the first amendment.' The filing argues Comey had 'an apparent financial incentive to stir up controversy' and that the post was designed to juice book sales for his 'eerily on-the-nose novel.' The book has sold 6,471 copies. PEN America's legal director Mara Gassmann issued a sharp rebuke: 'Citing a novel to save an indictment that is constitutionally dubious is a desperate Hail Mary and should be rejected.' The organization frames the prosecution as a dual first amendment problem — the original post is protected political expression, and conscripting fiction as prosecutorial evidence creates a chilling precedent for all creative work. Comey's defense team argues the post was protected speech that no reasonable observer would interpret as a personal threat of violence. They've moved to dismiss, calling the case 'vindictive and selective prosecution' that 'effectuates a years-long campaign by the president to use the criminal process to punish Mr Comey for his protected speech.' The Trump-Comey feud dates to the 2016 Russia investigation, which found 'sweeping and systematic' Russian interference but did not establish that the Trump campaign conspired with Moscow. The constitutional stakes here extend well beyond Comey. If courts accept fiction as corroborating evidence for threat charges, any author writing about political violence — which is most of American literature — becomes retroactively vulnerable. The mechanism is simple: write a novel with political themes, post something ambiguous on social media, and prosecutors can reverse-engineer intent from your creative work. PEN America's warning about 'extreme caution any time creative works are used to support criminal charges' isn't hypothetical advocacy — it's describing a doctrine that would make fiction itself a legal liability. The prosecution's weakest link is also its most revealing: 6,471 copies sold. The 'financial incentive' theory requires believing Comey risked federal charges to move units on a book almost nobody bought. The stronger read is that the novel citation is doing work the seashell photo can't do on its own — providing the narrative scaffolding prosecutors need to transform an ambiguous image into a 'true threat' that satisfies legal standards. What's being tested here is whether political hostility between a president and a former official can be laundered into criminal prosecution through creative interpretation of ambiguous speech acts. The 20-year question isn't about Comey — it's about whether the machinery being built to prosecute him becomes standard equipment for any administration that wants to criminalize dissent dressed as art.
