Positing a possibility for consideration:
Trump and Sessions seem to be on the outs and fighting, speculation is rampant that Sessions will resign or be fired, so Sessions calls a press conference and everyone in the media thinks that’s what it’s about. Coverage is massive. Sessions comes out and makes a few introductory comments and then reveals that the real reason for the press conference is the filing of numerous felony charges against the leakers and multiple members of the previous administration that conspired and colluded to harm President Trump and the functioning of the current administration. Arrests being carried out simultaneous with the press conference.
Thoughts?
It is exactly what Trump did with his major announcement at the hotel, where he then had admiral after general announce their support of him, playing the media like a well tuned fiddle.
But, my skepticism remains. Occam's Razor and all. Time will tell.
