Air quality in the U.S. has declined over the past 2 years since President Trump took office, reports AP.

The big picture: The EPA is expected to issue emissions regulations for coal-fired power plants on Wednesday that are more modest than an Obama-era rule that never took effect — the latest Trump administration move to loosen environmental rules. Trump previously said the U.S. has "the cleanest air in the world," and touted that it has improved throughout his presidency. Wildfires contribute to poor air quality, and the West Coast has seen 2 major seasons in 2017 and 2018, AP found.
