WASHINGTON, D.C. (AP)-- Attorneys general from 19 states and the District of Columbia say they'll go to court to stop a proposed rollback in mileage standards.
California and New York are among the states signing on to a statement Thursday pledging legal action against the Trump administration's action on fuel efficiency.
The group of attorneys general says in a statement that relaxing the nation's mileage standards will make Americans "breathe dirtier air and pay higher prices at the pumps."
The Trump administration says it wants to freeze mileage standards at 2020 levels.
The administration argues that should make new cars cheaper, and get newer, safer cars on the roads quicker as a result.
