US President Donald Trump has complained of his former security advisor John Bolton’s ‘nasty and untrue’ book on Twitter.

“For a guy who couldn’t get approved for the Ambassador to the U.N. years ago, couldn’t get approved for anything since, “begged” me for a non Senate approved job, which I gave him despite many saying “Don’t do it, sir”, takes the job, mistakenly says “Libyan Model” on T.V., and…many more mistakes of judgment, gets fired because frankly, if I listened to him, we would be in World War Six by now, and goes out and immediately writes a nasty and untrue book. All Classified National Security. Who would do this?” he tweeted.
