> Our elected congress blocked it. That is their role.

So in a Republic, the President has the right to issue decrees. That's what makes it the executive branch. Congress can make laws that block specific things but they would need to pass legislation? And assuming this power is granted on the constitution, they can't change this (easily).

> That is exactly what they do.

They rule if the president can issue that decree, no? They don't have the ability to change any of that?
