I thought I read something when Trump first made his statement to the effect of: immigration on ANY group can be halted if there was a perceived threat to the country from this group.
I hope I wasn’t dreaming this, because it would certainly make banning muslims perfectly legal.
Having said that, it would be impossible to find out who was a muslim and who wasn’t. STOP ALL IMMIGRATION for awhile. See my post #15 for details.
I think I saw this quoted earlier, and looked it up again.
