"Sen. Kamala Harris (D-Calif.) sent a letter to the Department of Justice’s (DOJ) inspector general Friday requesting he probe the basis for the department's antitrust investigation into four automakers working with California to reduce car emissions.

“In an expression of hostility towards California’s regulatory authority, the Trump administration has launched a multi-pronged assault on California’s framework with the four automakers,” Harris, who is also running for president, wrote to Inspector General Michael Horowitz.

Harris added that she has “serious questions about whether federal law enforcement is being used to coerce the four automakers to abandon their efforts to make cleaner, less-polluting vehicles” and asked Horowitz to “investigate the purported grounds for the Justice Department’s investigation of the four automakers.”"
