GM's Reinvestment in GM Plants

Phil Abou: GM and Ford can only get pulled up in the valuation dynamic. Mary Barra, I've got a question for you regarding Twitter. When you tweeted about the spaces that you're going to do with Elon today, that was the first time that you were back on Twitter since October 27th,. At that time, GM also discontinued advertising on the platform. Are you back on Twitter? Is GM going to continue its advertising?Mary Barra: We want to find a solution that's good for our employees, good for the company because we need to continue to reinvest. And right now we've made important announcements about reinvesting in these plants.
