NC states:  What concerns me is the phrase âother persons who may pose a threat to national securityâ in this directive. Itâs not defined so it can be defined indiscriminately.  What does it mean to pose a threat to national security? Wouldnât open borders pose a threat to national security?  Do we not have enough tools already established in our Constitution to monitor and track terrorist suspects?  I think so!  Can you see this directive in the hands of Obama who has Muslim ties?  Preside
