STOP WASTING TAXPAYER MONEY.  All the arguments Chin makes in this challenge is nonsensical, even to an elementary school-aged person.  WE HAVE MAYBE A FRACTION OF TOURISTS FROM THESE NATIONS.  NATIONAL SECURITY FAR OUTWEIGHS THE POTENTIAL FOR LOST REVENUE FROM THESE TOURISTS.  And on top of all of this, THESE SIX NATIONS WERE CHOSEN UNDER TRUMP'S PREDECESSOR, OBAMA, and with that this Executive Order merely reinforces that prior position.  AGAIN, PLEASE STOP WASTING TAXPAYER MONEY.
