"Fifteen states and two cities sued the Environmental Protection Agency (EPA) on Tuesday for declining to tighten air quality standards for ozone pollution, the main ingredient in smog.

According to a statement, the states and cities argue that “the EPA conducted a flawed and unlawfully biased review” and that “the available science clearly demonstrates the need” for stronger standards.

“We’re going to court today because of the undeniable harm that ozone pollution has on kids playing soccer near highways and parents scraping together money they don’t have to pay for asthma medication,” California Attorney General Xavier Becerra, President-elect Joe Biden's nominee to serve as Health and Human Services Secretary, said in a statement."
