Since everyone coordinated with Trump in the Tower...the Tower cannot be excluded as a place subjected to surveillance.
These people were being tracked...and for no security reason...therefore, it WAS unlawful.
Everybody up to and including the janitors in Trump Tower know about this. The question is what is going to be done about it? The Marxists will do everything to delay and obfuscate until they can get back in a position of some power and then sweep it down the memory hole or turn it over to Winston Smith and Julia.
