You know, Executive Orders are supposed to be only for carrying out laws already passed by Congress (and signed by the Prez).
That would include the U.S. Constitution, which was passed and ratified long ago.
Since Donald Trump is interested in writing Executive Orders to do what the law already says, is there any reason he can't simply issue an EO declaring all so-called "gun control" laws are in violation of the 2nd amendment to the U.S. Constitution, and are now null and void?
Federal, state and local.
No.
Because an executive order can ONLY instruct the executive branch on how to apply or enforce laws.
He could order the FBI not to prosecute people for simple possession of a firearm, but can't do anything about California shitting all over the Constitution with their laws. Only the court can act on that. Which is WHY it was so important to elect Trump, so that he could appoint honest men like Judge Gorsuch.
Technically, the Constitution lays out the powers of the federal government. One of which is it's inability to infringe upon the right to bear arms. Therefore, the feds can't prohibit the right to bear arms.
It also states that all powers reside with the states unless specifically granted to the feds via the Constitution. Unfortunately, the SCOTUS has basically ignored this on multiple occasions. Abortion and marriage being 2 high profile cases.
DJT could order federal enforcement agencies to ignore federal gun restriction statutes and rules with no consequence. Does Congress have the right to strike down all gun control laws has never been tested. Typical SCOTUS rulings hold that fed law trumps state law.
That is why a Constitutionalist SCOTUS is so important. Washington is filled with egos and power hungry individuals. Without the check of an honestly objective court, the rights of all Americans are in peril.
