It is getting hard to know what to believe. We often hear people make accusations, even unsubstantiated ones, even unbelievable ones, and we can dismiss them as fiction, or fantasy. But we aren't used to hearing such bold claims from the President of the United States. In the form of a tweet. But that is what we awoke to this weekend, with Donald Trump tweeting the wild accusation that President Obama wiretapped Trump Tower during the campaign. He went on to refer to Obama as a bad guy, and compared the so-called scandal to Watergate. Trump has offered no proof, but isn't afraid to make the claim. Of course we have heard this before. Trump previously tried to tell us the election was rigged, that millions of illegals voted, that his inaugural crowd was bigger, that Barack Obama wasn't even born in this country. It seems the more Trump tweets, the more we ignore him. Even his own White House didn't issue any follow up statements to his wiretapping yarn. Fellow republicans said little on the campaign trail. It seems that these days when the President of the United States makes bold claims, America is largely choosing to ignore them. But how are we to know when we should listen?
