Believe it or not?

Our Constitution States:
We the People of the United States, in Order to form a more perfect Union, establish Justice, insure domestic Tranquility, provide for the common defense, promote the general Welfare, and secure the Blessings of Liberty to ourselves and our Posterity, do ordain and establish this Constitution for the United States of America.
The United States Constitution lists the “Protections” for “ourselves”
We the People are the “ourselves”
American People are the “ourselves”…That simple!
NO WHERE does it say it applies to people entering our Country.
NO WHERE does it state your protected by it by entering via a Visa.
NO WHERE does it indicate visitors to the USA are covered by it.
If it did protect all who simply enter the USA?
Then it would logically protect them all in while still in their own Countries..It does not!
Illegal immigrants are not protected by our Constitution.

People visiting the USA are not protected by our Constitution.

People on any type of visa entering our Country are not protected by our Constitution.

That simple.
So yes, it is then Legal to Bar whom ever we desire from entering our Country….That simple!
Donald Trump is right on…He just forgot to say WHY HE IS…That simple!
