If a school superintendent did this everyone would

Flip out!

Tells principals to bid and purchase all school books and curriculum. Drives up prices. They spend the school funds on buying and superintendent confiscates it all and gives it to his favorite principals.

People would be screaming bloody murder that their kids are losing out on resources that belong to them and the superintendent would probably be fired!

Yet Trump getting away with it! Makes governors waste time and resources just to confiscate the items and pass it out as he sees fit.
