The Justice Department opened a criminal investigation to determine whether John Bolton, a former national security adviser, revealed illegally classified information in his recent book “The Room Where It Happened,” the New York Post reported.

John Bolton worked as a national security advisor for the Trump Administration for nearly a year and a half from April 2018 to September 2019. 

According to a Fox News article, Trump asked for his resignation in September 2019 as he ‘disagreed strongly’ with the advisor, mainly on international policy issues.

At the end of January, when the impeachment trial against President Trump was still in progress, Bolton’s book “leaked” and some media such as the New York Times (NYT) obtained a copy. The left-wing NYT published that Bolton said in his book that Trump asked the Ukrainian government to investigate the Bidens in exchange for financial aid, one of the two charges on which the impeachment was based.

Trump was acquitted of all charges in the Senate on February 6, 2020.

Trump reprimanded Bolton in a tweet when the book became known in the mainstream media:

Earlier in June, the administration tried to block publication of the book to verify that there was no sensitive information revealed. A federal judge rejected the request arguing the book had been leaked and that many parts were already published.

As a first step, the justice department subpoenaed the book’s publishers Simon & Schuster, to review all their communications with Bolton.
