This will probably get flagged, but if you read this, spent a few minutes trying to understand the gravity of this specific EO. Every federal employee even in independent agents must and will jump when Trump says so. Even if he asks them to do something illegal (close the congress! Jail a democrat!), they must follow his orders. Because HIS interpretation of the law cannot be superseded.
What is an “independent agency”? Which branch of the government is that a part of? Which electoral representative do they report to?
If he wanted to fire anyone who disagreed with him, this EO wouldn’t have been necessary. With very few exceptions, executive branch employees serve at the pleasure of the President.
This is how it is, how it has been, and is entirely consistent with the Constitution.
So, if not that, then why issue this EO?
First of all, it’s a statement: “Resistance to this agenda from within the executive branch will not be effective”
Secondly, it helps ensure that when the President issues a statement, it’s not immediately met with bureaucrats making statements to the contrary.
