It’s literally the first sentence of Article II! “The executive Power shall be vested in a President of the United States of America.” Article II doesn’t even talk about an “executive branch.” It assigns powers and responsibilities to the President.
It’s an extremely easy to understand structure that has been obfuscated during the 20th century. The constitutional actors are: the President, the 100 senators and 435 Congressmen, the 9 Justices, and Article III judges. They hold all the powers of their respective offices.
Can Congress appoint employees to be part of the Supreme Court, and provide for them to exercise judicial powers independently of the Justices? Of course not! Can Congress delegate to a staff of employees the power to make laws independently of the Congressmen? No! Obviously not! That would be absurd.
The executive branch isn’t any different.
