"To provide for calling forth the Militia to execute the Laws of the Union, suppress Insurrections and repel Invasions;"
The Congress has "provided forth" certain restrictions, including the Posse Comitatus Act. It's not a blank check.
I was referring to the use of the militia as proscribed in the Constitution. The regular military is not authorized in the Constitution for use in enforcing the law, but it certainly can be used to protect our borders. The Posse Comitatus Act only restricts the regular Army and Air Force from engaging in law enforcement which is actually redundant since the Constitution does not grant power to use the regular military for law enforcement as I noted.
