Good point.
All it takes is one mole with the WH router password, then anyone with a cellphone near the WH, or a guest etc. is a potential leaker.
Replace routers, have a trusted admin enter PWs into machines as needed.
Or machines with embedded code to monitor activity or even transmit. Even if the President doesn't use email, everyone else does, even his closest advisors.
I mean go ahead and color me a conspiracy nut but why else would Obama replace all the PCs in the WH and upgrade Internet connection? Sure the hell wasn't to help President Trump.
Do you think for one minute that Someone has already searched the WH form top to bottom ,very crack and crevasse for hidden bugs. Would it be possible that some of the bugs were internationally left in place for specific info to be leaked. Would that not be controlling the info or press? Think out side of the box. That is what TRUMP Does!
