The biggest problem with Trump is his mouth is not connected to his brain much of the time, a malady even I have to admit.However his Muslim comment about restricting their "coming to America"and deporting those here illegally happens to follow existing law under the McCarren/ Walters Act of 1952. You know the one Carter used to eliminate Iran from sending people to the US and returning many already here illegally. 

And who complained about Carter doing what Trump says he wants to do?

Bad mouthing the family of an American Muslim soldier was the height of stupidity.
