How Trump is rolling back Obama's environmental rules
Our thought bubble: The big question looming over much of this debate is whether the administration looks to repeal rules only, or eventually replace them. So far it's a mixed bag. Regardless, the process is long and litigious. Repealing most rules will take at least a year, and replacing them even longer, because each step requires a proposal, public comment period, two White House reviews and then a final version. Along the way, legal and political pushback is certain, possibly prolonging things.
