Republican presidential candidate Donald Trump's proposal for suspending immigration from parts of the world with a history of terrorism could have a legal basis, but his assertion that it be part of a broader ban on Muslim immigrants makes it constitutionally untenable, legal scholars say.
The new twist in Trump's anti-Muslim rhetoric came in the aftermath of a weekend shooting massacre at a Florida nightclub by the American-born son of Afghan immigrants.
In a fiery speech on Monday, he expanded on his proposed temporary ban on Muslims entering the United States, vowing if elected to halt immigration from any area of the world where there is a "proven history of terrorism" against America or its allies.
