The National Enquirer bought the rights to Karen McDougal's story of her affair with Donald Trump and then hid it. This strategy is known as catch and kill. The alleged purpose was to help a friend, Donald Trump, by hiding the story of the McDougal affair keeping it from the public eye during the presidential election.
This is why the affair is a story, not because Donald Trump allegedly had the affair but because of the elaborate mechanisms used to hide the affair.
This news begs the question: What other elaborate schemes is Trump using to create propaganda or create "fake news?" Stories like this one show that Donald Trump is willing to go to any lengths to lie to the American public. His acts of deception show us he is a dangerous deceiver.
