“Somebody, we dont know who yet, informed President Trump, then candidate, that Trump Tower had been bugged and they moved campaign functions out of there pronto.
Somebody, we dont know who yet, kept newly elected President Trump constantly informed of what was happening within the FBI.”
Admiral Michael Rogers informed President Trump of the surveillance of Trump Tower.

Why did he not stay and fight for the truth to come out and protect the POTUS from the coup?................
