What Trump did was violate his Presidential Oath:

"...I do solemnly swear (or affirm) that I will faithfully execute the Office of President of the United States, and will to the best of my Ability, preserve, protect and defend the Constitution of the United States."..."

The Constitution provides first amendment right of free speech.  Trump telling a private organization to punish citizens of the United States for exercising that right is in direct violation of the Oath and arguably subversion to the United States.  He should be impeached for this action...not commended.  You flag-wavers sure don't care about the laws of the land, do you?  Or are you just too ignorant to understand what and why the founders of this country did what they did?
