Are you sure?

...the Congress may also overturn an executive order by passing legislation in conflict with it or by refusing to approve funding to enforce it. Because the president retains the power to veto such a decision, however, the Congress usually needs a two-thirds majority to override a veto and truly end an executive order.
Pretty sure..
I remember reading about this some time ago, and I will have to see if I can find the source again..
The premise was that most executive orders go through (become "law" ) only because no senator bothers to challenge the president's authority to put it into effect..
But sometimes, Senators DO object to an executive order, and when that happens, it does NOT automatically become law..
So, when I say just a few senators, I mean that it takes more than just one, but not a 2/3 majority of the senate to make an objection to a proposed executive order..
IIRC, there is also a time factor..
The Senate is required to make their objections within a specific time frame as well..
Failure to do so means the executive order becomes law, "without comment" from the senate..
I will attempt to research and validate my claims..
