In this Wednesday, April 6, 2016, file photo, Republican presidential candidate Donald Trump speaks during a campaign rally, in Bethpage, N.Y. Trump says he would create coal-mining jobs as president, and he criticizes Hillary Clinton for saying “we’re going to put a lot of coal miners” out of work. Trump, however, has yet to explain exactly how he will revitalize Appalachia’s coal industry. (AP Photo/Julie Jacobson, File)
