This is a big one. Congress tried to write the law on a way that restricted the Presidents ability to choose who runs these agencies. SCOTUS said NO! This will apply to other agencies . Like, the Fed!

The Fed is a little different. It's a private bank, outside of the executive branch, that was established by an act of Congress in 1913.

Going back to McCulloch vs. Maryland during Andrew Jackson's term, the Supreme Court has consistently recognized Congressional power to form central banks (under the elastic clause and coinage clause of the constitution).
