As the channel clarifies, such a decision was made to avoid information leaks.
It is noted that now the employees who Trump personally appointed have access to the president’s conversations, including National Security Assistant Robert O'Brien, his deputy Matt Pottinger, Secretary of State Mike Pompeo and White House chief of staff Mick Mulvaney with his deputy Rob Blair.
In September, media reported that the White House restricted staff access to recordings of Trump's negotiations with foreign representatives.
Politico also wrote that the US president was discussing the possibility of looking for media informants in the White House using lie detectors, as the head of state is “very concerned about leaks about him.”
In September 2018, publications reported that Trump suspected his entourage of involvement in the leak of data from the White House. According to a source from Axios, the American president is inclined to believe in a conspiracy against him.
After publishing an article in The New York Times on September 5, where an anonymous author who called himself a “senior official from the Trump administration” said he was “part of the resistance inside the White House,” the editorial office received an official request for information about the anonymous author. The basis of the request was motivated by "maintaining national security."
The article was about "Donald Trump's paranoia." In particular, the anonymous author claimed that the American president did not trust people so much that in 2017 he compiled a list of people who might have been involved in the leak of data from the White House.
