No details yet but General Motors will announce plans today to invest a billion dollars in its U.S. plants today, something it’s reportedly been planning for months. The plans will reportedly maintain or create about a thousand jobs. Some of the money will go into Michigan plants, but beyond that we have no detail. Edmunds-dot-com Senior Analyst Jessica Caldwell says it reportedly has nothing to do with tweets from Donald Trump threatening to impose 35% tariffs on vehicles made in Canada or Mexico. She says the Trump tweets may be changing the way they deliver the good news, but not the news itself.
