Well, maybe Trump is a truther but he's not well known for stating the truth. When he's not making outright lies, he distorts. No surprise that conservatives claim to own the "truth". After all they represent the wealthy class, a group that knows the power of misrepresenting facts. Trump aligns perfectly with Orwell's picture of rule by convenient ignorance of facts or downright lies.
