Nov. 11, 2019–The U.S. Justice Department has issued civil subpoenas to four major automakers, demanding that they disclose details on a deal struck with California in July to follow strict vehicle emissions standards, reported Reuters.

The Trump administration in September issued a determination that California cannot set its own vehicle emission standards and zero-emission vehicle mandates and is investigating if the companies engaged in anti-competitive conduct in striking the deal.

The Justice Department has issued civil investigative demands to Ford, Honda, BMW, and Volkswagen.
