On Sunday, US President Donald Trump once again attacked his former National Security Adviser John Bolton, calling him one of the stupidest people in Washington.

Trump asked, through his Twitter account, "What can Bolton, who is one of the stupid people in Washington, know?"

"Wasn't he the one who spoke foolishly in a televised statement about the Libyan solution to describe what the United States would do to North Korea?" He added, "I have a lot of other stupid Bolton stories."

This is not the first time that Trump has launched a stern attack on Bolton, as he has previously said about him that he is one of the most stupid people he has worked with in the government, considering that the man is "sullen and boring and has added nothing to national security except by saying (Let's go to war)." .

For his part, Bolton responded to Trump's comments, describing them as adolescence and non-presidential, and said, "I will not go down to his level."

Earlier, former White House National Security Adviser John Bolton said in June that President Donald Trump is not fit for the position and does not have the ability to perform the task, after the judiciary rejected Trump's attempt to prevent the publication of Bolton's book that criticized his administration, and Trump said that Bolton He broke the law by posting very confidential information.

The book - titled "The Room Where the Event Happened" - records events that the author says took place behind the scenes during Bolton's tenure as National Security Adviser between 2018 and 2019.

Bolton drew in his memoirs a bleak picture of Trump, saying that he was trying to harness US foreign policy to serve personal interests, including his re-election, explaining that Trump - on the sidelines of the G20 summit in Japan in the summer of 2019 - asked his Chinese counterpart Xi Jinping to help him win the US presidential election.

The book also accused Trump of ignorance on a number of issues in international politics, and that officials in the president's administration fluctuated between deep anxiety and mockery of the president's words and actions.
