Opponents say it stops the experts from regulating harmful pollutants.
One could also say it stops UNELECTED supposed experts from regulating what they have NO power to regulate unless given that power by the “people” through it’s elected representatives. IOW no such legislation is necessary, the Congress need only to ACT. Get rid of the EPA. Good Luck! We could add the DOJ to the list, while we are at it, and keep right on going for good measure saving the budget, oh there isn’t one, the republic, oh that went out with Woodrow Wilson, or was it good ol Abe?
