This doesnt make sense.
No, makes perfect sense. We spy on them, they spy on us. We have high-tech listening devices that can penetrate any network and eavesdrop; so do they. Every country spies on every other country - some do a better job than others, but we and the Brits have the best toys.
GCHQ, the British equivalent of our NSA. They did it with their toys.
How can a foreign govt wiretap someone here, anyone?
Happens all the time.
Is this done, and our FBI and CIA and NSA turn their eye to it?
Yep.
No, my point is the FBI, CIA, NSA must of known about the spying and turned a blind eye to it.
OTOH, Trump was a private citizen and not in the confines of the WH, so he would be easy prey for someone like the Brits, but who ordered them to do this?
If Obama did he should come down hard on the guy. I mean have someone else present an iron clad case of it.
Remember, they didn’t expect Trump to win.
