While I do think some of the regulations should have been rolled back, some of them should not have been. Just because Obama implemented them does not make them wrong. There was a mad rush to do so with no thought given. The chemical plant that exploded in Texas was protected from more regulation by Republicans. It seems the Democrats have more ammo fro 2018.
Please show us your reliable source and link proving that it was Republicans who protected that chemical plant from more regulations. What regulations did they not comply with or were they perfectly legal?
