Trump blasted Bolton's book on Twitter last week, calling it "a compilation of lies and made up stories, all intended to make me look bad."

WASHINGTON, June 23  -- The memoir of John Bolton, U.S. President Donald Trump's former national security adviser, was released on Tuesday, days after a federal judge denied the Trump administration's request to block its publication.

"There is simply no precedent for a former top administration official publishing a book about a sitting president that is as damning as John Bolton's," a CNN report commented on Tuesday.

Meanwhile, many local analysts say the revelations of Bolton's book, titled The Room Where It Happened, are not likely to make much difference among most Republicans behind Trump.
