A former national security adviser John Bolton has just been issued a formal threat from The Trump White House to keep him from publishing his upcoming new book, "The Room Where It Happened: A White House Memoir," according to a new report by CNN.
According to a disclosure by New York Time, Bolton, base on a manuscript of his new book released said he will be willing to testify if subpoenad by the Senate in the ongoing senate trial of US president Donald Trump.
In Bolton's new book it is alleged that he said Trump was willing to tie $391m worth of military aid to Ukraine in exchange for opening investigations into Political rival Joe Biden.
While Trump has decided to exert some Executive privileges on Bolton to stop him from testifying in the senate and on Wednesday launched a scathing attack on Bolton, accusing him of lying to sell his book, and now it has been revealed that the White House has warned Bolton from publishing the book saying it contains details that will affect 'national security'.
In a letter to Bolton's lawyer reported by CNN, a top official at the National Security Council wrote the unpublished manuscript of Bolton's book "appears to contain significant amounts of classified information" and couldn't be published as written.
The letter, which is dated January 23, said some of the information was classified at the "top secret" level, meaning it "reasonably could be expected to cause exceptionally grave harm to the national security."
"The manuscript may not be published or otherwise disclosed without the deletion of this classified information," the letter read.
Republicans insist they don't want witnesses in Trump's ongoing senate trial but with details of Bolton's book now out, some Republicans might join the Democrats to vote for witnesses to testify in the senate trial.
Trump is being tried by the Republican controlled senate after the Democrat controlled House of Representatives voted to impeach him for Abuse of power and obstruction of congress as regards a whistle blower report that the US president allegedly withheld military aid to Ukraine until he was assured that the country will open up an investigation into his political rival, Joe Biden.
