My bet is that Mike Johnson is delaying calling back the Congress in hopes that Trump declared Martial Law or calls on the Insurrection Art, so they do not have to disclose things.

I also bet that they will fake some violence the day of the next protests, which seem to be this weekend.

Also all the reporting about the troop deployment might drown out the news about the protests. Positive side effect for them.

I also suspect that Fox will then have a 24/7 WAR ROOM like broadcast, yelling at the "cowardly left who attacked ICE agents who try to save the country from illegal aliens" ...
