According to the agency, Trump said that the Sensei should begin an investigation to establish the identity of the author of the text, since the published material also touches on issues of national security.
On September 5, The New York Times published an article by an unnamed source from the US administration, who told about the sabotage of officials of Trump's decisions due to the fact that they do not share his views.
Later, the American leader said that the newspaper should, from considerations of national security, issue an official who is the author of the material.
