Is everyone in Washington writing a tell-all? It sure seems like it. Though it’s not surprising to see so many books about President Trump on the best-seller list, it is surprising that, barely two years into his term, so many of them are written by people who were once key players in his administration. Some are effusive: In “The Briefing,” Trump’s perpetually beleaguered former press secretary, Sean Spicer, called his boss “a unicorn riding a unicorn over a rainbow,” and Anthony Scaramucci, who was briefly the White House communications director, wrote in “Trump: The Blue Collar President” that for a “guy working in finance, who wanted to rise through the economic classes and reach for the Gold Ring, Mr. Trump was the Great Gatsby.”

Others are less flattering: The former F.B.I. director James Comey described the president as “unethical, and untethered to truth and institutional values” in “A Higher Loyalty,” and the onetime White House aide Omarosa Manigault Newman dubbed him “Twitter Fingers” in “Unhinged.”

Two more such books have just landed. “Team of Vipers: My 500 Extraordinary Days in the Trump White House,” a scathing West Wing exposé by a former communications aide, Cliff Sims, debuts at No. 4, and “Let Me Finish,” a largely laudatory memoir by one of the president’s former advisers, Chris Christie, enters the list at No. 5. (The Times called it “a superficial and ungainly book that tries to cover so many bases at once … that reading it is like watching an octopus try to play the bagpipes.”)

Want more? Next up is “The Threat: How the F.B.I. Protects America in the Age of Terror and Trump,” due later this month from the ex-deputy F.B.I. director Andrew McCabe. In March, Preet Bharara — who was a federal prosecutor for the Southern District of New York — will publish “Doing Justice: A Prosecutor’s Thoughts on Crime, Punishment, and the Rule of Law.” And the former national security adviser H.R. McMaster is also writing a memoir, “Battlegrounds,” which comes out in 2020.
