The basis for the Friday directive, the official added, is "national security concerns."
As is the border with Mexico, it is a matter of National Security.
And now we see some funds being freed up that needs to be re-deploied.
What President Trump can not do follows.
DOD issued Directive 5525.5, which outlines its policies and procedures for supporting federal, state, and local LEAs. DOD Directive 5525.5 prohibits the following forms of direct assistance: (1) interdiction of a vehicle, vessel, aircraft, or other similar activity; (2) a search or seizure; (3) an arrest, apprehension, stop and frisk, or similar activity; and (4) use of military personnel in the pursuit of individuals, or as undercover agents, informants, investigators, or interrogators. It is generally accepted that the PCA does not apply to the actions of the National Guard when not in federal service.22 As a matter of policy, however, National Guard regulations stipulate that its personnel are not, except for exigent circumstances or as otherwise authorized, to participate directly in the arrest or search of suspects or the general public.23
I don't see a thing in there about not building walls and fences to protect the intergriaty and security of the border.
But look at this...
As amended, Section 1004 authorizes the military to maintain, upgrade, and repair military equipment; transport federal, state, local, and foreign law enforcement personnel and equipment within or outside the United States; establish bases for operations or training; train law enforcement personnel in counter-drug activities; detect, monitor, and communicate movements of air, sea, and surface traffic outside the United States, and within 25 miles of the border if the detection occurred outside the United States; construct roads, fences, and lighting along the U.S. border; provide linguists and intelligence analysis services; conduct aerial and ground reconnaissance; and establish command, control, communication, and computer networks for improved integration of law enforcement, active military, and National Guard activities
All of it already established and authorized by none other that President Hussein.
