Michael Wolff, whose tell-all about Donald Trump's chaotic early days in the White House was one of last year's bestsellers, is to publish a follow up next month called "Siege: Trump Under Fire."
"Fire and Fury," the first of a string of books about the Trump presidency, was published in January 2018 and sold more than four million copies worldwide.
Citing dozens of anonymous insider sources, the book told the story of how the former real estate magnate and reality star stunned the world by winning the 2016 election, painting an unflattering portrait of a chaotic campaign and an incompetent president.
Trump dismissed the book as a "full of lies" and had his personal lawyer send a cease and desist order to the publisher, to no avail.
Wolff's publisher Henry Holt, a subsidiary of Macmillan, said that where "Fire and Fury" dealt with Trump's first year in the White House, the new book "reveals an administration that is perpetually beleaguered by investigations and a president who is increasingly volatile, erratic and exposed."
The book, to be released on June 4, starts out with Trump's presidency going into its second year and ends with the publication of the report by special counsel Robert Mueller about Russian interference in the 2016 election.
