You've just blindly asserted a whole bunch of things without laying out any sort of supporting arguments. What exactly makes the GAO not "part of the executive branch" ? My understanding is that "branches" are merely a framework used for describing government, not a prescriptive org chart. And how do the GAO's employees get paid, if not by a system that is now under the control of the autocratic Executive?

>> (a)The Government Accountability Office is an instrumentality of the United States Government independent of the executive departments.
The law establishing it also establishes it as independent.
The branches are explicitly defined in the Constitution.
