In most cases, a President-elect is a member of government and already has an existing security clearance. For Donald Trump, we've got a very different situation. While some would say Trump has essentially been "vetted" by the public and media, he's also been highly secretive of his foreign influence and financial history. The allegations of sexual assault would also raise flags to an adjudicator for an average worker.
Does this group think that Trump will actually undergo a clearance investigation, or has he already been vetted by public opinion? Secondly, if investigators uncover things on Trump that would normally raise red flags for an average worker, would they pose problems for the President-elect?
