Jimmy Carter banned immigrants from IRAN not of a certain religion, which shows your ignorance on this topic. Cruz has already suggested doing what Carter did and ban people from terrorist supporting countries, which is legal and would stop most muslim immigration.
It is illegal to discriminate or persecute based on religion. That is the law and the reason that banning muslims is absurd and will never work.
Not to mention, do you actually think muslims will tell you that they are muslims if we ban muslim immigrtation if they are intent on attacking our country?? If you’re that naive then maybe our litmus test should just be to ban all muslims admitting to future attacks on the U.S. That makes about as much sense.
Our constitution does not cover anyone but citizens.
Yes, a president CAN limit immigration for ANY reason.
Look it up.
Sorry, the President can ban any person or group if he deems them unfit or dangerous to our country. He has that power.
