Former President Donald Trump, as many presidential candidates tend to do ahead of an election cycle in order to garner extra attention, is set to release a new book next month.

The impending release of that book has already sparked panic among a number of celebrities and politicians, as it will publicly expose the prior private correspondences Trump had with dozens of other famous individuals over the decades, the Conservative Brief reported.

Trump’s “very fascinating life” on display

Set for public release on April 25 by Winning Team Publishing, former President Trump’s newest book “Letters to Trump” — which is available for pre-order — “captures the incredible, and oftentimes private correspondence, between President Donald J. Trump and some of the biggest names in history throughout the past 40 years!”

Breitbart reported that the book features dozens of “letters that Trump sent and received from interesting, famous, powerful, and influential people over the years, both during his time as president and for the decades leading up to his historic White House run in 2016.”

The book includes correspondence with such wide-ranging figures as royal world leaders like Queen Elizabeth II and Princess Diana; cultural figures like Clint Eastwood, Oprah Winfrey, and Michael Jackson; sports stars like Shaquille O’Neal; and former presidents Richard Nixon, Ronald Reagan, George H.W. Bush, George W. Bush, Bill Clinton, and Barack Obama. It also has correspondence Trump had with foreign leaders like Chinese President Xi Jinping, North Korean leader Kim Jong-un, and former Brazilian president Jair Bolsonaro.

In an exclusive interview with the outlet, Trump said, “I think they’re going to see a very fascinating life. I knew them all — and every one of them kissed my ass, and now I only have half of them kissing my ass.”

Former friends “changed” as soon as Trump ran for office

The former president’s eldest son, Donald Trump Jr., told Breitbart, “My father has lived an amazing life and has been around some of the most interesting people in the world.”

“It’s amazing how quickly their adoration of him changed when he ran for office as a Republican. “Letters to Trump” shows you exactly how they felt about him and how phony their newfound disdain truly is,” he added.

The founder of Winning Team Publishing, Sergio Gor, similarly told the outlet, “Long before entering the White House, Donald Trump was already corresponding with countless famous individuals,” and added, “We went through thousands of letters and were amazed to see decades of correspondence with Kings, Presidents, Hollywood Stars, athletes, and business titans. No one else has such a collection, and we are thrilled to have the opportunity to share it with the world.”

Publisher insists “actual or implied consent” was obtained

Newsweek reported that not everyone who is featured in Trump’s new book is thrilled at the prospect, including comedian Jay Leno, who said in a statement through a representative that he “did not release, nor authorize any use of any letter to Mr. Trump.”

Likewise, a spokesperson for failed 2016 Democratic nominee Hillary Clinton, Nick Merrill, told the outlet that Trump hadn’t sought Clinton’s permission to publish their prior private correspondences.

“Nothing says deeply-insecure-has-been quite like publishing private correspondence with the hope that people will believe you once garnered respect,” Merrill said on behalf of Clinton. “Feels like the adult equivalent of when a toddler proudly presents you with what they’ve done on the potty.”

There is some debate over whether writers or recipients of letters have the right to publish such correspondence, and in some instances, copyright law could result in lawsuits, but a spokesperson for Trump’s publisher believes that all of their bases are properly covered in that regard.

“The book comprises of a unique collection of correspondence either from President Trump or from public officials both foreign and domestic, or from private individuals,” the spokesperson told Newsweek. “For those in public office at the time, no copyright protection arises. For the last category, Winning Team Publishing has either actual or implied consent for their publication.”
