Troops at the border for a political stunt is only just THE BEGINNING. Next he will order troops to surround the White House and hide therein so no one he dislikes will come in. Think I'm joking? What's the diff in moving soldiers as a craven VERY EXPENSIVE political stunt to win an election and moving soldiers to protect the president from facing the consequences of his multifarious criminal treasonous traitorous illegal self-serving decisions? Both are ILLEGAL. ILLEGAL is what the john of don delights in being and doing.
