Politically appointed U.S. environmental officials last year overruled concerns of career scientists about air pollution in a Wisconsin county where U.S. President Donald Trump has pushed for a factory to be built by Foxconn Technology Co., newly released internal emails show. Trump has been a supporter of the Taiwanese technology giant Foxconn building a flat screen factory in Racine County, Wisconsin, a project the company said could create up to 13,000 jobs. He announced the project at a ceremony in 2017 and has claimed it is proof of his ability to revive U.S. manufacturing. Former Wisconsin Gov. Scott Walker, a Republican, helped secure about $4 billion in tax breaks for the project.

But Racine County has suffered some of the state¡¯s worst cases of smog, also known as ozone, pollution that causes premature deaths from lung and heart complications.

The emails obtained by the Sierra Club and Clean Wisconsin under a freedom of information request show Trump administration officials, including then-administrator Scott Pruitt, overruled career EPA scientists to exempt Racine County from a list of counties that break smog standards. That has freed Foxconn from having to make millions of dollars in pollution control devices, if the project is eventually built.
