Environmental Protection Agency head Scott Pruitt on Tuesday formally announced plans to roll back Obama-era fuel efficiency standards, saying the move met a central promise of Donald Trump’s campaign.

Scott Pruitt: “This is another step. This is another step in the president’s regulatory agenda—deregulatory agenda. … The president, again, is saying, 'America is going to be put first.' And we have nothing to be apologetic about.”

Pruitt made the remarks at the EPA’s headquarters in Washington, D.C., after Chevrolet dealers objected to Pruitt’s plans to use a Chevy salesroom in Virginia as a backdrop to his announcement. The event was attended by auto industry lobbyists, and only a handful of reporters were allowed to attend.
