White House readies final review of new mpg rules

Trump administration officials defended their controversial proposal to freeze fuel efficiency requirements at 2020 levels at a congressional hearing on Thursday and said the proposal would be submitted to the White House for final review in the coming weeks.

The administration has rebuffed requests from automakers and some lawmakers to make a last-ditch effort to reach a deal with California to extend national standards after it ended talks in February. The administration plans in the coming months to finalize a dramatic rewrite of fuel efficiency standards through 2026 that would also strip California, the most populous state, which wants stricter rules to fight climate change, of the right to set its own, tougher emissions rules.
