"Democrats Slam Trump’s Rollback Of Fuel Economy Rules"

"A cross-section of Republicans expressed support for the president’s move."

"Congressional Democrats slammed President Donald Trump’s proposed rollback of auto efficiency standards Wednesday, while Republicans wholeheartedly supported the move.

With the GOP holding majorities in both chambers of Congress, Democratic opposition is unlikely to affect the plans from the Transportation Department’s National Highway Traffic Safety Administration. Still, Democrats will try to make their voices heard on the matter.

Rep. Debbie Dingell (D-Mich.), long a champion of the major automakers that call her state home, said the rollback threatens certainty for the industry."
