What such power is Trump using?
He has been using the power of his office to attack businesses left and right. To the point, it has resulted in billion dollar swings in stock value. A single tweet by Trump cost Amazon $6 Billion dollars.
https://mashable.com/2017/08/16/donald-trump-amazon-tweet/This is a bullying tactic that almost equates to a protection racket. It is virtual window breaking- you'll meet our demands or we'll break your windows (or worse). It is the high tech, government sponsored shake-down of private business.
One that the Commander in Chief of the United States Armed Forces has zero Constitutional authority over.
Conservatives should be screaming at any government official doing this, even if that official has a R behind their name. We screamed when Obama used the power of his office to attack private businesses.
