Took you all that verbiage to point out that the USA is a republic governed by a constitution?? Thats something that American kids learn in grade school.
So tell us, constitutional expert, what is the limit of Congresses power concerning the executive and what is the constitutional limit on Trumps power over the executive? You are familiar with Collins v Yellen, right? How about Federalist 70? Obviously you must be, based on your assertions in the OP and your evident agreement with Mr. Krugman, a notorious leftist Democratic shill?
BTW, Mr. Krugman asserts meretricious behavior on the part of Trump. Do you have facts to support that assertion?
