President Donald Trump told leaders of the world's top automakers on Friday that he wants to see more cars built in the United States as his administration weighs plans to reduce gas mileage and pollution requirements enacted during the Obama administration. Trump said in a meeting in the Roosevelt Room of the White House that he intended to discuss environmental controls, fuel efficiency standards and the "manufacturing of millions of more cars within the United States, for Michigan, for Ohio, for Pennsylvania" and states like South Carolina and North Carolina.
