WASHINGTON — The White House, blindsided by a pact between California and four automakers to oppose President Trump’s auto emissions rollbacks, has mounted an effort to prevent any more from joining the other side.
Toyota, Fiat Chrysler and General Motors were all summoned by a senior Trump adviser to a White House meeting last month where he pressed them to stand by the president’s own initiative, according to four people familiar with the talks.
But even as the White House was working to do this, it was losing ground. Yet another company, Mercedes-Benz, is preparing to join the California agreement, according to two people familiar with the German company’s plans.
Mr. Trump, described by three people as “enraged” by California’s deal, has also demanded that his staffers step up the pace to complete his plan. His proposal, however, is directly at odds with the wishes of many automakers, which fear that the aggressive rollbacks will spark a legal battle between California and the federal government that could split the United States car market.
