WASHINGTON — The Justice Department has opened a criminal investigation into whether President Trump’s former national security adviser John R. Bolton unlawfully disclosed classified information when he published a memoir this summer, a case that the department opened after it failed to stop the book’s publication this summer, according to three people familiar with the matter.
The department has convened a grand jury, which issued a subpoena for communications records from Simon & Schuster, the publisher of Mr. Bolton’s memoir, “The Room Where It Happened.” In the book, Mr. Bolton delivered a highly unflattering account of his 17 months working in the Trump administration.
The investigation is a significant escalation in the fraught publication of the book. The Trump administration had sought to stop its publication, accusing Mr. Bolton in a lawsuit of moving forward with publication without receiving final notice that a prepublication review to scrub out classified information was complete. The director of national intelligence referred the matter to the Justice Department last month, two of the people said.
Mr. Bolton has denied that he published classified information. Representatives for the Justice Department, the Office of the Director of National Intelligence and the National Security Council declined to comment.
Lawyers for the National Security Council and the Justice Department expressed reservations about opening a criminal case, in part because Mr. Trump’s public statements made it seem like an overtly political act, according to two officials briefed on the discussions. Others noted that a federal judge this summer said that Mr. Bolton may have broken the law, and that the case had merit.
Mr. Bolton had agreed to let national security officials review any book he might eventually write before publication in order to make sure that it contained no classified information. The department accused Mr. Bolton of giving Simon & Schuster permission to publish his book before he had official signoff that his prepublication review was complete. It also sued to halt publication.
But the department sued Mr. Bolton just a week before his book was set to hit retailers in June, and a federal judge said that it was too late to keep the book out of the hands of readers.
“With hundreds of thousands of copies around the globe — many in newsrooms — the damage is done,” wrote Judge Royce C. Lamberth of the Federal District Court of the District of Columbia.
But in his opinion, Judge Lamberth also suggested that Mr. Bolton could be criminally prosecuted if he did indeed allow the book to be published before he received final official notice that the government’s review was complete.
“Bolton has gambled with the national security of the United States,” Judge Lamberth wrote. “He has exposed his country to harm and himself to civil (and potentially criminal) liability. But these facts do not control the motion before the court.”
After viewing classified declarations and discussing them in a closed hearing, Judge Lambert also said that he was “persuaded that defendant Bolton likely jeopardized national security by disclosing classified information in violation of his nondisclosure agreement obligations.”
Mr. Bolton’s lawyer, Charles J. Cooper, rejected the judge’s view. “We respectfully take issue, however, with the court’s preliminary conclusion at this early stage of the case that Ambassador Bolton did not comply fully with his contractual prepublication obligation to the government,” Mr. Cooper said in a statement this summer. “The full story of these events has yet to be told — but it will be.”
At issue is whether Mr. Bolton received signoff from the government that prepublication review process was complete.
Mr. Cooper has accused the administration of slow-walking the process in order to keep Mr. Bolton from revealing embarrassing information about Mr. Trump. The administration has said that Mr. Bolton unlawfully disclosed classified information.
In an email, the National Security Council’s top official for prepublication review said she was satisfied with the edits that Mr. Bolton had made to address her concerns about classified information.
But the White House initiated another review without notifying Mr. Bolton, and the official involved in that review said in an affidavit that he found multiple instances of classified information in the manuscript as part of that process.
Even though Mr. Bolton did not receive a final approval letter from the White House, he told Simon & Schuster to publish anyway.
Separate from the criminal investigation, Mr. Bolton still faces civil litigation that could force him to forfeit the proceeds from his book to the government, as punishment for breaching his prepublication review agreement.
Judge Lamberth, who is overseeing the litigation over the book proceeds, wrote in June that Mr. Bolton could have sued the government instead of unilaterally publishing if he was unhappy with the delay.
“This was Bolton’s bet: If he is right and the book does not contain classified information, he keeps the upside mentioned above; but if he is wrong, he stands to lose his profits from the book deal, exposes himself to criminal liability, and imperils national security,” he wrote. “Bolton was wrong.”
