Republican presidential nominee Donald Trump manned the fry station at a McDonald's in Pennsylvania on Sunday before staging an impromptu news conference, answering questions through the drive-thru window. As reporters and aides watched, an employee showed Trump how to dunk baskets of fries in oil, salt the fries and put them into boxes using a scoop.
