My thought exactly. An executive order can only be undone by a vote of congress or by the next president.
I can see that executive orders are how presidents send directives to officials within the executive branch. Executive order is just a fancy term for internal memo from the president in that context.
But note that the Supreme Court busted President Truman for sending executive orders to people outside the executive branch, the Supremes clarifying that executive orders do not have the force of law unless they are legislatively supported by Congress.
Youngstown Sheet & Tube Co. v. Sawyer
But even when an executive order has the legislative backing of Congress, Congress must be able to justify such legislation with its constitutional, Article I, Section 8-limited powers which corrupt Congress cannot do with many of the laws that it makes these days.
These days FReepers probably know more about Congress’s Section 8-limited powers than Congress does.
