I think there are plenty of Military Intelligence Official in Trump’s corner, and I am pretty sure that they know quite a bit about who the bad actors are.
This dust up with Flynn should have trapped some of them, and the news media too. It is illegal to leak this info and it is illegal to print it. If the FBI or Justice department has executed the right warrant, they could have already seized the records, and legally the people involved are not allowed to report it either, so we won’t know for quite a while if ever, but if some prominent reporter or CEO of network resigns or retires, just be a little suspicious.
