Former senior intelligence officials said in interviews that during the Trump administration, highly classified intelligence about sensitive topics, including about intelligence-gathering on Iran, was routinely mishandled. One former official said the most highly classified information often ended up in the hands of personnel who didn’t appear to have a need to possess it or weren’t authorized to read it.
That former official also said signals intelligence — intercepted electronic communications such as emails and phone calls of foreign leaders — was among the type of information that often ended up with unauthorized personnel. Such intercepts are among the most closely guarded secrets because of what they can reveal about how the United States has penetrated foreign governments.
A person familiar with the inventory of 15 boxes taken from Mar-a-Lago in January indicated that signals intelligence material was included in them. The precise nature of the information was unclear.
