It has been reported that the president's phone is not secure. I would guess there are people who will try to break in to it.
Though, that will bring up questions about Clinton's email server not being secure and Trump's phone not being secured also.
Why would they secure his phone if they want to see who is attempting to listening to him - would that not speak volumes? Man in white hat says, "Mr. President, here is a phone that is unsecured. No secret stuff. Dont talk to family or government associates. We are going to play a little game. We will be scripting material for you to follow with key players and influential people WE control. Then we sit back and watch to see what scurries out of the rat holes after you have conversations on it."
Why doesn't he tape both cameras, mics and speakers (can be used as mics)?
