"WASHINGTON - The number of unhealthy air days in major cities across the United States has risen sharply over the last two years, even as emissions of key pollutants continue to slip, according to data released by the Environmental Protection Agency on Wednesday.
The data comes as the administration of President Donald Trump seeks to highlight major improvements in America’s air quality since the 1970s as proof the country can protect the environment and boost the economy at the same time.
Trump said in a White House speech last week his administration “has made it a top priority to ensure America” has the cleanest air and water."
