Totally agree with this, the US has turned into an administrative state, which is far from the vision enacted by the founding fathers in which Congress and/or states regulate. Today congress has chosen to forsake their main role as legislators by creating unelected unaccountable bureaucrats with, essentially, unchecked law making abilities.
That said, I would like congress to take up the matter of clean air and water directly, instead of this cowering behind other agencies after abdicating of their duties.
