US air quality is slipping after years of improvement

There were noticeably more polluted air days each year in the president’s first two years in office than any of the four years before, according to new Environmental Protection Agency data analyzed by The Associated Press. The EPA quietly posted new air quality data online last month that shows a recent uptick in polluted days. El Paso, Texas, saw one of the biggest increases in bad air days from the mid-2010s among metro areas with at least 750,000 people.
