Observe the timeline:

YESTERDAY: Trump takes federal control of the DC police for 30 days, deploys the NG to secure DC, SecDef has unnamed “specialized military units” on standby.

TODAY: Trump notifies Smithsonian he will be reviewing their collections.

This means that Trump will have access to the Smithsonian tunnels beneath the National Mall, while he just so happens to have military presence and full control of DC. These tunnels could be used to mask the movement of troops, perps, equipment, etc.

I find the timing of Trump conducting a “comprehensive internal review” of the Smithsonian museums to be a little suspicious to say the least.
