And yet Article 2 Section 3 exists. Constitutional convention copy machine go Brrr. However I did exaggerate slightly for satirical effect. Maybe I should have just said "some alterations".
The Congress does not answer to the president. It is an independent institution. It does not convene and dissolve by presidential request.
Executive orders can be over-ruled by either of the other two branches of government
Veto power can be over-ruled by the congress.
Until recently, presidents needed congressional approval to make war. Now we skip that part and just don't call it a war.
