Trump's suggestion to use active duty military is hardly according to the constitution.

Donald Trump declares a national emergency
Presidential Powers: National Emergency
Unknown to most Americans, a parallel legal regime allows the president to sidestep many of the constraints that normally apply.
The moment the president declares a “national emergency”—a decision that is entirely within his discretion—more than 100 special provisions become available to him. While many of these tee up reasonable responses to genuine emergencies, some appear dangerously suited to a leader bent on amassing or retaining power. For instance, the president can, with the flick of his pen, activate laws allowing him to shut down many kinds of electronic communications inside the United States or freeze Americans’ bank accounts.
Other powers are available even without a declaration of emergency, i
ncluding laws that allow the president to deploy troops inside the country to subdue domestic unrest.
