Well the recent news is that Ford was scrapping its plans for the 2.5B plant in Mexico. That was the headline. If that news is accurate, then it has nothing to do with Ford moving truck lines to Ohio. It can only be attributed to Trump’s frontrunner status and his credible threat to put a hurt on Ford if they continue building plants in Mexico.
But there is no basis for that "recent news." All of the rumors floating around on the topic--including Trump's own tweets--are based on an article published on "Prntly" (whatever that is), which discusses the Ohio move, and suggests (wrongly) that the Ohio move means that Ford has cancelled the 2.5B plant.
In fact, there is ZERO evidence that Ford is scrapping the 2.5B plant, and Ford has released a statement saying that it is NOT doing so.
