In the 2016 campaign, the “National Enquirer” ran damaging headlines about Hillary Clinton and GOP opponents of Donald Trump. Chief Executive of the National Enquirer’s Publisher, David Pecker, is now cooperating with Federal Prosecutors. A former Editor at the National Enquirer, Jerry George, tells Ari Melber that Pecker “certainly” knew incriminating things about Trump that have not been published and says stories about Trump that the Enquirer did not publish are “certainly embarrassing” and those involving “the actions of his children” including Ivanka Trump and Jared Kushner, get close to “criminal activity”.
