Donald Trump tweeted a warning shot across GM's front bumper on Tuesday, November 27, 2018, threatening to pull all U.S. subsidies for America's largest automaker if its plans to slash jobs and production at North American plants prove to be a precursor to building interconnected electric cars in China.
