The president has asked top executives to detail how the automaker settled its lawsuit with the Environmental Protection Agency and what they have learned from the probe, The Hill has learned.

The White House is also expected to unveil details on the agreement that was reached between the two companies, which were brought together after years of litigation over the pollution and toxicology of the carmaker’s air pollution-contaminated vehicles.

Trump is expected to ask top executives at GM, Volkswagen, Ford, Honda, Audi, Hyundai, Toyota and Fiat Chrysler to explain what they learned during the investigation into the pollution.

The president’s request for details came a day after his administration sent letters to 11 automakers and two government agencies asking them to explain why they have not provided information about the settlement that was signed last week.

The White House did not provide specific details about why they did not cooperate.

White House press secretary Sarah Sanders on Thursday also sought to reassure Americans that the administration has not reached a “hard-and-fast” deal with automakers.

“The president has been clear that he’s focused on getting these companies to do the right thing, and he’s also made it clear that his administration will not stand idly by and allow them to fail,” Sanders said.

The automakers are expected to provide detailed responses by the end of the week.
