text: I would seriously like to know, which exact law the President of the USA broke by signing the executive order banning muslims (but not religious minorities persecuted in these 7 countries)  from those 7 countries to enter USA for 90 days? 
  
  Tell me, which law of the USA guarantees the foreign aliens (or non-citizens of the USA) the right of entry into the USA? I would really like to get the reference to such a law.
