All signs point to a major military buildup for something big tomorrow, but I don't know what.
Also keep in mind that the USMC's Commandant, who is usually pretty active on social media, has gone completely dark in the last couple of weeks. I also have inside sources that tell me that there are indeed Marines in DC right now, just not what they're doing. Understandable, since they have to maintain OPSEC.
Trump still technically controls the armed forces until 12 PM EST on the 20th. So if they're going to make a move, they have about a day to do it.
It's also possible that they're acting on their own initiative.
