Former national security advisor John Bolton is running into a new roadblock with the release of his “tell-all” book.

According to the The Hill, an official on the National Security Council claimed that “significant amounts of classified information” are in the manuscript written by Bolton — and the NSC will seek to block it from being published.

In fact, according to a message written by Ellen J. Knight — the NSC’s senior director for records, access, and information security management — to Bolton’s lawyer, he could be in serious legal trouble if he published his book in the current state it’s in.

“Under federal law and the nondisclosure agreements your client signed as a condition for gaining access to classified information, the manuscript may not be published or otherwise disclosed without the deletion of this classified information,” Knight wrote.

The book, which claims that President Donald Trump threatened to withhold aid from Ukraine should they not investigate Hunter Biden, is causing some GOP senators to defect from their previous stances of disallowing witnesses from attending the trial.

And on Tuesday night, Majority Leader Mitch McConnell reportedly told GOP senate members he longer had the votes to restrict witnesses from attending the trial, which may throw the entire impeachment process for a loop.

“McConnell told his members that he did not yet have enough votes to be able to kill the witness vote, expected Friday, according to people familiar. Yet several 2020ers spoke, saying they’re ready to move on to final vote, move on from the trial,” Washington Post reported Seung Min Kim tweeted.
