My guess (and I hope this isn’t true) is that the briefing will include the plans to smuggle in human carriers of very bad diseases as “suicide biological bombers.” (think Ebola)
The Obama efforts to bring in people with resistant TB and Zika was a dry run to test the distribution portion (moving infected people all over the US) of the plan and get limited data on retransmission.
This makes sense. Easier to smuggle than nukes
