At the moment when Our President gets in hot water on some other issue I'm sure he will release exactly how he found out about Trump Tower being bugged. He has evidence, I'm certain.
For those of you who live in the middle of our country and have been staring at cow asses your whole life let me tell you a little about the mind of a company president or owner in N.Y. after 9/11. They dedicated their life to protecting their company's information and their employees lives. The President of Cantor Fitzgerald and his talk about the survival of his company and the support of the families who lost loved ones spurred many like Trump to increase security. If you think The President is bluffing that is your rite. I believe he has the goods on the big O and is just waiting.
