Francis Chung/E&E News Rioters who charged the Capitol on Jan. 6 hoping to preserve Donald Trump's power may have actually hurt the former president's environmental legacy. It comes down to a technical provision in the Congressional Review Act that requires hard copies of regulations be sent from the Senate parliamentarian's office to committees before they are formally "received by the Congress."
