If you knew anything about the government of the United States you'd realize that its principles are founded on a system of checks and balances. Without said checks and balances you have the potential for authoritarian rule. There is supposed to be opposition in government, and that is exactly what Yates was doing. Even during her swearing in, in 2015, the incoming Attorney General asked her if she would be willing to oppose an order if it is unconstitutional, and she rightly responded "no". The INCOMING GENERAL, who TRUMP SELECTED, was HAPPY WITH HER RESPONSE. 

What is happening is a complete takeover of government by a small faction of elites. All you who wanted a much smaller government have blindly elected an authoritarian who is wielding dictatorship-force. Congratulations, you know nothing about the government you call your own.
